One Direction have topped the MTV Video Music Awards (VMAs) picking up three trophies for What Makes You Beautiful.

The group took home best new artist, best pop video and most share-worthy video.

They also performed their latest song, One Thing, for fans at the ceremony in Los Angeles.

"Thank you so much! We have grown up watching this show and to collect one of these [awards] straight away is incredible," said Niall Horan.

Simon Cowell, the band's manager tweeted the group saying: "Congratulations 1D. I'm very proud of you. Celebrate!"

One Direction, who got together on the X Factor, became the first UK pop group to debut at number one on the US album chart earlier this year with Up All Night.

More than 10,000 fans are estimated to have turned up to see the stars' first live TV performance in the US when they appeared on NBC's Today Show in New York.

They sold 176,000 copies of the album in the US in a week and it topped the digital charts minutes after its release.

Winners

Rihanna had the most nominations going in to the event with five although she only won one award in the end, for video of the year.

"I love you guys! This is awesome," said Rihanna, as she collected her trophy.

On her way from collecting the prize she was congratulated by her ex-boyfriend Chris Brown, who previously pleaded guilty to assaulting the pop star before the Grammy music awards in 2009.

Green Day's Billie Joe Armstrong also appeared at the ceremony, where he was mobbed after inviting fans to come up on stage.

He looked fully recovered after being taken to hospital earlier in the week.

Alicia Keys was joined on stage by US Olympic gymnast Gabby Douglas, who back-flipped while the singer performed her new single Girl On Fire.

Performers also took the opportunity to crowd surf, with Taylor Swift, Lil Wayne and host Kevin Hart all diving off the stage.
