Usain Bolt parties with Swedish handball players and Jessica Ennis enjoys Stone Roses gig after Olympic wins
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.
'I had to come,' Jessica told The Sun.
'I think they're brilliant.'
