Harry Styles is a right little celebrity mingler isn't he? Fresh from stirring up a massive food fight in Rita Ora's G-A-Y dressing room with bezzie mate Nick Grimshaw last weekend, the threesome headed out to London's Mahiki last night for some more tom fooolery.

For starters, it looks like Hazza's about to give a swift backhand to the arse of the unsuspecting chap infront of him. Although on second thoughts, that looks like it's Grimmy, who's probably pretty well braced for some arse action.

New favourite gal-pal Rita Ora headed out in a camo jacket over her animal print frock, with matching red nails and handbag.

Well, someone's gotta bring a bit o' class to the joint, right?

The amigos were said to be out celebrating Rita's album release and headline show at the Scala, with Mahiki tweeting that Conor Maynard and Cara Delevigne were also shmoozing it up over a coconut cocktail inside.

Hazza's probably set for a lie down on the sofa with a couple o' Yazoos today then.
