REVEALED: Inside Prince William's Russian birthday blowout
Prince William marked turning 30 by downing flavoured vodkas, Now can reveal.
The Royal took wife Kate Middleton and 30 friends out for a belated birthday bash at Russian-themed restaurant Mari Vanna in Knightsbridge on 2 July.
And it seems the booze was in full flow, as a fellow diner tells Now: 'He and his mates were clearly enjoying a good party.
'Wills definitely looked the worse for wear after enjoying a few flavoured vodkas.'
Things got interesting when the guests gave William, who turned 30 on 21 June, his gifts - one of which was an apron featuring a male model's ripped body in blue trunks.
Another onlooker says: 'He clearly loved it. He was still wearing the apron when he came out into the smoking area at 3am... It must've been one hell of a party!'
There was one person in less of a party mood, though.
Kate, 30, decided on an earlier night, leaving at 1am while William stayed on until just after 3am and is thought to have continued the party at a friend's house.
