The lawsuit, which was filed in California by musician Will Loomis, names Jessica Cornish, Universal Music Group, Lava Records, and Universal Republic Records as defendants in a case that suggests large portions of his 2008 song 'Bright Red Chords' were taken for 'Domino'.

Chris Arledge, the man's lawyer, said in an official statement: "Mr. Loomis never consented to the use of his song and we look forward to obtaining an appropriate remedy from the court for this clear infringement."

Loomis has since uploaded a video to YouTube of his track played side-by-side with 'Domino' so that the striking similarities can be heard publicly.

Listen to both songs in his clip below:

The 'Laserlight' star is currently plotting the follow-up to her debut smash 'Who You Are' and she told the Daily Star about her collaboration plans.

Jessie J isn't just hoping for Rihanna and Beyoncé however - she also has Brits Ed Sheeran and Tinie Tempah in mind too. She said:

"It took me seven years to get people interested in the first album, so the pressure weighs heavy on my shoulders with the anticipation of the second. I want to get Ed Sheeran and Tinie Tempah on there, but I'd also love to work with Rihanna and Beyoncé. It has to happen organically, depending on who's around."

As previously reported, Jessie J was recently quoted as saying that she got locked inside a toilet at a recent Jay-Z and Kanye West gig - ultimately being set free by Jay-Z's crew.

The singer is quoted by The Sun as saying she attended the gig with will.i.am and a friend - only to find herself locked in the toilet as the gig started.

However, Jay-Z's entourage came to her rescue, knocking down the door and setting Jessie and her friend free. She said:

"I went with Will.i.am to the first (Jay-Z and Kanye West) Watch The Throne show in London. I somehow managed to find myself walking into the stage with them all - Will, Kanye, Jay-Z, Kim Kardashian. I was like 'Wow, what a crew', then me and my friend got stuck in the toilet."

She continued: "We nipped in to do our make-up and my friend knew the door was broken but locked it anyway and said, 'Babe I think I've broken the door'. They’d been on for one song, we could hear them and it got to about 15 minutes and Jay’s security came in and they literally kicked down the whole door."

The singing star has enjoyed a successful time recently, with a number of chart smashes and an appearance on the inaugural UK version of The Voice as a coach.

She recently announced a 2013 UK and Ireland arena tour called 'Nice To Meet You' - and she took to Twitter today (June 22) to announce an autobiography of the same name.

Jessie J will release the book in September this year, allowing fans to gain an insight into the life of their idol.

Tweeting about the book, Jessie J said:

"My OFFICIAL autobiography is OUT in September and is called 'Nice to meet you' :D #exclusive #nicetomeetyoutour2013 AND #nicetomeetyoubook."

The 24-year-old, who yesterday performed her number one hit, ‘Price Tag,’ with Rizzle Kicks at the Capital Summertime Ball, told Grazia magazine that she considers herself very lucky to be a performer for a living:

“I get to go out on stage and see thousands of people singing the words to my songs and that is for me 'the dream experience.'

“Well, that and playing at being a lion with my nephews. You've got to keep it real.”

The Voice coach, who yesterday revealed she would be up for a collaboration with Katy Perry, also went on to confess that she doesn’t see anything wrong with occasionally acting like a diva:

“Sometimes you have to be a diva. All the artists I admire, from Madonna to Whitney to Mariah, have been called divas.

“If you are strong, if you have vision, if you are an artist, you have to do what you believe in. And if you get called a diva for it, so what?”

The singer is taking part in Capital FM's Summertime Ball gig at the London stadium on Saturday (June 9), alongside such acts as Justin Bieber.

Jessie J recorded a special message in an empty Wembley for her fans as she prepares for the show - asking them to create a great atmosphere during her performance. She said in the clip:

"I want to tell you guys that I cannot wait to see you on the 9th June here, when you guys are going to be filling the seats. I can't wait to see you guys there and sing really loud."

As previously reported, Jessie J recently extended her 2012 UK and Ireland summer tour due to phenomenal demand, adding a Nottingham date.

The 'On The Floor' rapper, who is also performing at the exciting event on June 9, recently said of Jessie J:

"I want to let her know how much respect I've got for her and on top of that I want to let her know that I think she's very, very sexy."

She was flattered by his public display of affection and during an interview with the station's James Barr suggested that their backstage areas should be adjacent so they could "get a party started with a Kodak":

"Put him next to me. Let's get a party started with a Kodak. Why not? I don't know if Pitbull's my type but you know."

The Summertime Ball will take place this coming Saturday at London's Wembley Stadium and is also set to feature live performances from the likes of Coldplay, Rita Ora and Justin Bieber.

The two singers are at the top of their respective games at the moment, with Jessie J leading the way in British pop music and Perry about to launch her 'Part Of Me' 3D film.

Speaking to Glamour magazine, Jessie J praised Perry for her "dignity and strength" and reveals that she takes inspiration from the 'Firework' singer. She said:

"Her hard work, her dedication, and how she deals with having the world stare at her every move, personally and professionally, with such dignity and strength, is inspiring."

Jessie J also spoke about her last twelve months in the music business, recalling her highlights. She said:

"There have been so many professional highlights. But headlining at the O2 in London and being the first UK female to have had six Top 10 singles from one album has to be up there. I was so shocked when I was told that."

The singer was speaking to Capital FM about their upcoming Summertime Ball event on Saturday (June 9), which Jessie J is scheduled to perform at.

She expressed her excitement at playing the Wembley Stadium show and said that her last year in the music business has been "crazy". She said:

"I can't wait to do the Summertime Ball. Last year was a blast and the whole year that I've had then has just been crazy. I just can't wait to show the Summertime Ballers what Jessie J's all about and got."

She concluded: "The Summertime Ball is going to be a special one."

Jessie J meanwhile last night (June 4) expressed her joy at performing for the Queen at her Diamond Jubilee Concert, calling it a moment she will never forget.

The 24-year-old, who has previously declared plans to work with the ‘Lego House’ singer, told The Independent that she expects him to have a long and successful career:

“Ed Sheeran's album + is beautiful just because it's purely about his voice and his great songs. It's really honest and any guy that can hold a stage by himself with a guitar and nothing else is someone that is going to be around for a long time."

The ‘Price Tag’ star, who like Sheeran, will be performing at the Queen’s Diamond Jubilee concert on Monday night, went onto reveal what she’s currently watching on the box and on the big-screen:

“I have a hard drive that my friend made for me with all my favourite television programmes on that I take around with me. That was a great gift! The shows I enjoy watching the most are Crime Scene Investigation, Come Dine with Me, The Voice and Summer Heights High.

“I recently saw the American Reunion sequel which was funny. I also managed to catch The Girl with the Dragon Tattoo, with Daniel Craig. It was a very intense film, with lots of twists. That's what I like about films on the whole. I like them to keep you on the very edge of your seat.”

Whilst appearing on Kiss FM, the singer was asked who out of will.i.am, Danny O'Donoghue and Sir Tom Jones she would snog, marry and avoid.

Jessie J plumped for The Script's O'Donoghue in the kissing category, whilst she reckoned veteran crooner Tom Jones would be the best for marriage.

That means poor will.i.am was chosen as the one to avoid, but there's a reason why - he can take the rejection. Speaking about her choices, Jessie J said:

"Snog Danny, avoid Will and marry Tom. I love Will and he knows that and he can take it."

The 'Price Tag' sensation picked up the coveted 'Best Solo Artist' prize at the 2012 Glamour Awards, which took place yesterday in London (May 30), and while on stage to collect her trophy she told the audience:

"I've had so much fun. Last year I was a girl, this year a woman because I get my bum out more and I get an award and a goody bag."

She also took to social networking site Twitter last night and announced another extra tour date for 2013, telling her Heartbeats:

"I'm SO happy to tell you that due to incredible demand, I'm adding a further show at Nottingham Arena on Thursday 21st March 2013. The tickets will go onsale this Friday at 9am. Thank you so much again for your support and can't wait to see you there #nicetomeetyoutour2013"

Watch a brief interview with Jessie J from backstage at the 2012 Glamour Awards below:

The singer has unveiled a new gig at the Nottingham Arena after the first date proved so popular.

The new concert will take place on March 21 next year and tickets are on sale from Friday (June 1). Tweeting about the addition, Jessie J said:

"I'm SO happy to tell you that due to incredible demand, I'm adding a further show at Nottingham Arena on Thursday 21st March 2013. The tickets will go onsale this Friday at 9am.Thank you so much again for your support and can't wait to see you there."

The singer meanwhile had earlier tweeted a photo of herself rehearsing for the upcoming Diamond Jubilee celebratory gig in London, which can be seen below.

The singer picked up the Solo Artist of the Year gong at the event in London, which she attended.

Kelly Rowland meanwhile collected the TV Personality Of The Year award for her role on the last series of the X Factor.

Kylie Minogue bagged the Outstanding Contribution award due to her 25 years in the music industry.

Jessie J meanwhile tweeted a photo of herself at the event and later said:

"Tonight was very Glamourous... Lovely to have a night out with wonderful people and get dressed up. I'm going to celebrate my award with a early night *sort of* very needed x Goodnight x"

In a new interview with Grazia magazine, the 'Price Tag' star explained that she only asked for two items and both were incredibly low key so it's unfair for the press to make up exaggerated stories:

"There isn’t anything flash in my dressing room. No champagne. No yoga mats or anything. That was meant to be one of my diva demands. I did ask for a scented candle. I don’t think it’s too much to ask for a nice, relaxing smell in the room. I also asked for a lava lamp."

“When I was a kid, they used to have a room at Great Ormond Street Hospital where you’d go and chill out. It was full of lava lamps and water lamps and since then it’s always been a way to help me wind down. I never got one, and that’s OK."

Despite opening up about the things she asked for as a vocal coach on the popular talent show, Jessie J also questioned the limits of what's acceptable and what should be considered as too much where requests are concerned, and added:

“But is there anything wrong with asking for what you know is good for you? Does that make you a diva, a pain? Or does it make you someone who knows what they want?”
