Speaking to BBC Radio 5 Live, the 'Laserlight' songstress explained that she genuinely didn't think her music would enjoy such success, but she is so grateful for the support of her amazing fans:

"I didn't ever, ever think I'd have 7 singles, I kind of thought 3 and then we'd end it!"

When asked about her current role on The Voice UK, Jessie J admitted that it's definitely been an eye-opening experience although she wishes the press would focus on the positive side of the programme instead of always putting an unpleasant spin on stories:

"It's been really good, it's been a massive learning curve. One album out and I'm stting next to Sir Tom Jobes, Will.i.Am and Danny!"

"It irritates me because every interview I've done in the last week has been about the negative instead of the positive press. I'd like to hope to think I've brought to the table that it's important to be constructive and honest, but you know what... papers write crap all the time."

Nordoff Robbins provides music therapy to people in the hope that it will improve their general wellbeing, address emotional and behavioural difficulties and help them with confidence issues.

The 'Domino' superstar is set to be presented with the prize at the exciting ceremony, which will take place on June 29 at London's Hilton Hotel on Park Lane. A statement on Nordoff-Robbins.org.uk confirms:

 "Jessie J will be presented with the well-deserved Royal Albert Hall Best British Act Award, after ruling the charts with her smash hits such as ‘Price Tag’, ‘Do It Like A Dude’ and ‘Domino’."

She is also set to present the Lifetime Achievement award to composer Andrew Lloyd Webber, who picked her to star in the West End production of Whistle Down The Wind when she was just 11, and he revealed that he's looking forward to seeing her at the ceremony:

"It will be fantastic to see Jessie J again and I’m looking forward to celebrating with her and all the other award winners in June."

The singer has previously revealed that she is bisexual and explained to the magazine that her supportive family life has shown her that acceptance and love is something that should come naturally to people:

"You know what it is – I have such an amazing mum and dad who have been married for 32 years, and my sisters always made me feel like I was amazing. No one ever tried to suppress who I wanted to be. I never got embarrassed."

She also admitted that while she is currently unattached, she feels that sexuality "shouldn't define you" and thinks its important to stand up for your beliefs:

"I've never tried to make my sexuality something that's going to put me in newspapers or magazines,' she admitted. 'Sexuality shouldn't define you, it should be part of who you are. At the moment I'm single, happy and learning about myself. Music is the love of my life right now."

Although the vocal sensation announced plans to shave her head for charity last year, she explained to Glamour magazine in a new interview that it makes more sense for her to change her look with hair pieces to stop it getting damaged:

"It's tough to explain to people. When you have half an hour to be ready at four o'clock in the morning, you don't have time to get up and glue in extensions or blow-dry your hair." 

"A hairdresser who did my hair said, 'You, my darling, have something that we call 'successful' hair', which is basically battered hair that's split and falling out in the back because you've had to blow-dry it every day. I don't want my hair falling out, so I wear wigs!"

She also admitted that despite being a pop star she doesn't really immerse herself in the stereotypical lifestyle and isn't really a "party person" at all:

"I'm young, and having one drink is [enough]. My [calendar] is just unreal at the moment. I don't have time to be tired!"

"You need to choose when you have your celebration and make it special instead of going out every night and exhausting yourself. I'm not really the party person. I don't 'become myself' once I'm drunk. I don't use alcohol to be happy."

The pop sensation, who is currently working as a judge on the UK's debut series of the popular talent show, gave a stunning performance of the track and was even accompanied by some of Christina Aguilera's team members as backing singers.

Earlier this morning, Jessie J tweeted about being part of last night's live performances and explained: "Wow that was fun!!!!! The Voice USA!!!! Reppin for the UK! :D"

Other vocal coaches on the current U.S. version of The Voice also include Cee Lo Green, Maroon 5's Adam Levine and country star Blake Shelton.

The video for 'Laserlight', which is an anthemic track and features the French DJ, begins with the vocal superstar sat in the back seat of a car wearing a spiked leather jacket and moves to a movie theatre before cutting to the star in a shadowy room full of vibrant lasers.

It is a stylish offering and the visuals are particularly striking with the contrast of dark backgrounds with bright beams of light, and it will serve as the fifth single to be taken from Jessie J's debut studio album 'Who You Are'.

She also performed her first live gig last night (April 9) in Los Angeles and told her Heartbeats via social networking site Twitter that it "felt brand new" and was an "inspiring" experience.

37-year-old Phillip Sherriff was stabbed in the neck at the BlackBerry showcase on April 3 at Pulse nightclub in Southwark, but tragically his condition deteriorated over the weekend and he died from his injuries.

The 'Who You Are' songstress took to Twitter last night and shared her heartbreak with her followers:

"I am lost for words. All I can say is my thoughts, love and respects are with the family and children of the man who attended the blackberry gig last week who sadly lost his life this morning <3 So sad.."

As previously reported, it had emerged that a man was in a serious condition after being stabbed in the neck at a BlackBerry sponsored event in London on April 3.

It is said Jessie J had already performed at the event before the incident happened.

The BBC reports that 25-year-old Ashley Charles from Leicester has been charged with attempted murder in relation to the incident.

The victim, a 37-year-old man, remains in a serious condition in hospital.

Wiseman is set to tie the knot with JLS star Marvin Humes in the near future as they settle down into married life.

Speaking to the Sun, Murs joked that he's angling for an invite to Wiseman's hen party so that he can try his luck at a bit of romance himself - with Wiseman's bandmate Mollie King. He said:

"I'm going to try and find a way to get invited. That way I'd get to hang out with Mollie. She's lovely."

As previously reported, Murs recently spoke of his lack of luck when trying to entice females from across the pond. The Xtra Factor host is touring America with One Direction soon and admitted that he hopes the boys can teach him a thing or two when it comes to impressing ladies in the US.

As previously reported, a man was stabbed at a BlackBerry sponsored event on April 3 which Jessie J had earlier performed at.

The man remains in a serious condition, with another man arrested over the incident.

The singer was set to perform tonight at a MasterCard sponsored event in London, but it has been postponed to June 12, according to reports.

A representative for the event said in a statement:

"In light of the events, and out of respect to the person that was injured, MasterCard and Universal music have taken the decision to postpone the Priceless gig."
