Usain Bolt has been having fun

Sprinter Usain Bolt celebrated winning his London 2012 gold medal and setting a new Olympic record in the men's 100m event on Sunday by partying in his room with 3 pretty Swedish handball players.

Usain and the girls were joined by Jamaican decathlete Maurice Smith to pose for photos and mess around on Facebook and Twitter.

'A gaza we say hmmm mmm,' Tweeted Usain, 25, along with a photo of him and the girls making 'W' for winner signs with their hands.

Usain - who races in his 200m heat today - isn't the only Olympic star who's been celebrating success at the London 2012 Games.

Rowers Sophie Hosking, 26, and Mark Hunter, 34, have been partying with cyclist Dani King, 21, and other athletes at London's Chinawhite.

And British heptathlon winner Jessica Ennis, 26, joined cycling champion Bradley Wiggins, 32, at an intimate Stone Roses gig in London last night.

'I had to come,' Jessica told The Sun.

'I think they're brilliant.'
