MTV Europe Music Awards 2011

Lady Gaga struggles to keep a grasp on her impressive cache of awards - four in total, including best female, best song and best video for Born This Way, and biggest fans (in a nod to her devoted "little monsters" following).

Collecting the gong for best song, Gaga told the audience, "I knew that this was very special when I wrote it, and I didn't know when I first started out as a songwriter how special it would be. It's the most important single to me."

Katy Perry opts for a bubblegum look. She later picked up an award for best live act.

"It's easy to buy a song, download a song, steal a song. But to buy a ticket and see an act live is real commitment," she told the crowd.

Jessie J was nominated for two awards at the ceremony - best new act and best push.

"It feels very humbling to be here after 12 months of craziness," she said.

Although she missed out on both gongs, Jessie J still ruled the pink carpet in a range of outfits, including this leopard print gown by Dolce & Gabbana.

Jessie also introduced a video tribute to Amy Winehouse at the awards.

"I don’t think I’d be here tonight if it wasn’t for her," she said of the late singer. "I hope I put the world’s thoughts into my speech because I really wish she was still here."

Heroes actress Hayden Panettiere was upstaged by a male streaker as she was about to present the award for best song to Lady Gaga.

The incident led to a storm of comments on Twitter. "Naked Guy was obviously staged. How would someone not catch him before he got on stage?" one user wrote.

Disney actress Selena Gomez hosted the evening's festivities.

Selena's boyfriend Justin Bieber picked up two awards at the bash, including best male and best pop act.

"There’s been a lot of crap on the internet lately," he told reporters, in reference to stories that he has fathered a secret love child.

On A Mission singer Katy B keeps things simple in head-to-toe black.

The Baywatch star later flirted with Gaga on-stage, saying, "All the nominees are very beautiful women. In fact there are a lot of beautiful women backstage in the dressing room next to me.

"In fact, I drilled a hole in the wall – in case they want to watch me changing."
