The pair previously teamed up for the track 'Everything Has Changed', which featured on the country-pop star's 2012 record 'Red'.

The 'A Team' man meanwhile confirmed that there was another collaboration with Swift sitting on his phone.

Speaking to Noise11, Sheeran suggested that another duet could be written whilst the pair tour North America together this year. He said:

"My second album has taken shape recently. I don't know if there will be any collaborations on it."

Speaking about another duet with Swift, Sheeran said: "You never know. I'm on tour with her for six months. I'm sure the guitars will come out at some point."

The first wave of nominations have been released for this year's ceremony, which is taking place on August 11.

One Direction are nominated for the Choice Music Group prize, whilst their singer Harry Styles is up for the Choice Male Hottie and Choice Smile gongs.

The news seemingly cements Styles as the leading icon from the group, who also feature the likes of Niall Horan and Liam Payne.

Other nominees for the ceremony include Justin Bieber in the Choice Male Artist and Male Hottie categories.

The hotly contested Choice Female Artist section will see Selena Gomez, Demi Lovato, P!nk, Rihanna and Taylor Swift battle it out.

More details about the ceremony, including further nominees and its performers, are due to be revealed soon.

The ceremony will be held at the Bridgestone Arena in Nashville on June 5 and will also see live sets from the likes of Taylor Swift, Miranda Lambert's band Pistol Annies, Hunter Hayes and Luke Bryan.

The CMTs are set to be hosted by Hollywood actress Kristin Bell and she will be joined by co-host Aldean, who will share the presenting duties.

Underwood, who is an Oklahoma native, took to her official Twitter page yesterday (May 21) to send a message of love and hope to those impacted by the devastating tornadoes:

"Growing up in tornado alley, you always know what could happen...it doesn't change how devastating it is when something does happen. #pray I'm thinking about and praying for my beautiful home state and the people in it tonight."

The 'Come & Get It' beauty has been single for a little while now and explained to Miami's Y100 radio station that tying the knot at 20 is something she no longer has any interest in:

"Oh my god no ... I'm not even 21 yet ... I'm sure I was that little girl that wanted to be married at 20, but no that's definitely not anything I want on my radar. I have so much to have fun with and experience."

Both Gomez and Bieber were at the 2013 Billboard Music Awards last night (May 19) and while they embraced backstage, hitmaker Taylor Swift could be seen walking past and grimacing at their hug and cheek kiss.

Watch her latest music video, which is for 'Two Black Cadillacs', below:

ABC's three-hour telecast of the event averaged 9.47 million viewers and earned a 3.6 rating/10 share among the key 18-49 age group.

The show aired live from Las Vegas and had a fair amount of drama, from Justin Bieber getting booed while making an acceptance speech to singer Miguel trying to jump between stage platforms and landing awkwardly on an audience member's neck.

Other unusual highlights included 'Bawitdaba' star Kid Rock slamming some of the event's performers' artistic integrity on stage, telling the crowd and viewers alike: "Let's give it up to people lip-synching under pre-recorded music!'

Songstress Taylor Swift walked away with an astounding 8 prizes, while UK boyband One Direction were presented with 3 titles ( Top New Artist, Top Pop Artist and Top Duo/Group).

Watch clips from the Billboard Music Awards below:

The band won the Top Group, Top New Artist and Top Pop Artist awards at the ceremony in Las Vegas last night (May 19).

The news seems to have sat well with Niall Horan, who gushed on Twitter today (May 20):

"Wow ! Wake up and find out that we've won 3 billboard awards! Can't believe it! Thank you so much best fans ever ! Love you soo much xxxxxxx."

He continued: "Top group, top new artist, top pop artist! You guys are the best! Thanks very much! Means so much!"

Other winners on the night included Taylor Swift, who bagged eight awards, and Justin Bieber, who won three.

The former meanwhile made headlines after being seen sticking her tongue out at an embrace between the Canadian and former girlfriend Selena Gomez.

The Canadian and the 'Come & Get It' star are said to be single after years of dating but they shared an awkward hug backstage at the Las Vegas event.

It looked as if Bieber went in for a kiss on the lips, but Gomez sidestepped it and planted one on his cheek.

As the embrace took place, Taylor Swift happened to be walking by after entering the room with Gomez - and she stuck out her tongue in apparent disgust at the embrace.

The 'Red' star meanwhile also snubbed a question about Bieber during a press conference at the event.

She was asked about the 'Believe' singer winning the Milestone award - to which she said: "Can we have another question?"

Swift trumped the Canadian in the award stakes, winning eight gongs in total.

The star-studded event took place in Las Vegas as the music industry came together to honour its top stars.

Swift won eight awards - Top Artist, Top Billboard 200 Album, Top Female Artist, Top Billboard 200 Artist, Top Digital Songs Artist, Top Country Artist, Top Country Album and Top Country Song.

Justin Bieber meanwhile picked up the Top Male Artist, Top Social Artist and Milestone gongs.

One Direction snapped up the Top New Artist, Top Pop Artist and Top Duo/Group awards.

Other winners on the night included Nicki Minaj, who bagged three prizes, and Madonna, who took to the stage to collect the Top Touring Artist award.

The event saw live performances from the likes of Christina Aguilera, Jennifer Lopez and Prince, who won the Billboard Music Icon gong.

Speaking as part of her collection for shoe brand Keds, Swift explained that her style is "feminine, experimental and classic," and that she will take inspiration from the world around her when putting together an outfit:

"I like to wear in the spring, and I'll admit I'm obnoxious like this, I like to dress like a mini-Easter egg. I get really excited about seasons changing. I'm self aware about it but I'm excited about it. I like pastels and bows. I like to incorporate the summer wardrobe along with some things for spring into the overall look."

The beauty added that like any other girl she has looks she will always return to: "I'll have these style epiphanies. When I was 15, I realised that I loved the idea of a sundress and cowboy boots and that's all I wore for, like, two years. Try everything because you might not like it today but you might want to wear it tomorrow. If you find a look you keep going back to it then it might just be your personal style."

During an interview with Billboard, the 'I Knew You Were Trouble' songstress explained that she loves Icona Pop's 'I Love It', which became popular after it was used in an episode of 'Girls':

"I’m also absolutely smitten with 'I Love It' by Icona Pop. It’s the way reckless abandon sounds in my head. I play it right before I go onstage."

She confessed to loving ballads and named collaborator Ed Sheeran as one of her favourite artists of the moment: "I love that ballads became huge hits this year and that unexpected songs and artists got lots of airplay. Ed Sheeran, the Lumineers and fun. are some of my favorites right now, and they’ve all had big hits with songs that have substance and real instruments. I like it!"

When asked if she's into EDM or house music, Swift added: "I don’t like to feel like I’m in a club when I’m in my car and I turn on the radio. Anything that ceases to be a song and just sounds like house music kind of stresses me out."

Watch Icona Pop perform their smash hit single, 'I Love It', below:

The US duo will play the song - which features on the latter's album '#willpower' - at Sunday's (May 19) Billboard Music Awards.

The track will be just one of many high-profile collaborations set to take place at the Las Vegas awards ceremony.

Christina Aguilera, Pitbull and a mystery guest will perform 'Feel This Moment', whilst David Guetta, Ne-Yo and Akon will run through 'Play It Hard'.

Jennifer Lopez and Pitbull will perform new single 'Live It Up', whilst Nicki Minaj and Lil Wayne will take 'High School' to the stage.

All these collaborations come in addition to a host of solo performances, with twelve acts lined up to play on the night.

Prince, Taylor Swift, Ed Sheeran and Selena Gomez are all among the list of guests due to perform at the star-studded event.

Lamorne Morris (pictured below), who plays the character of Winston, has admitted to Vulture that he's desperate for Rihanna to sign up for the programme and he wants her to play his love interest:

"I would like to see him in a relationship. Rihanna's trying to act now. Let's bring her on."

"She would [have to] play somebody. I wouldn't want her to play [the real] Rihanna, because Rihanna is probably a little wild for Winston. She would walk all over Winston."

Last year, Rihanna starred in the science fiction war movie 'Battleship' although her role as Petty Officer Cora 'Weps' Raikes only won her a Razzie Award for Worst Supporting Actress.
