Jaime Winstone in a Bungalow state

JAIME WINSTONE showed her partying stamina remains undiminished, leading a 12-hour bender for pal Nick Grimshaw’s  24th birthday party.

The young actress was still partying at 8am today after a long dinner and cocktails session in Bungalow 8 nightclub. Donkey Punch star Winstone was without boyfriend Alfie Allen as she ordered vodka from the bar.

The party, at the trendy Covent Garden club, quickly turned into the coolest bash in town. Kelly Osbourne mingled with Johnny Borrell, who was chatting to Seb Chew and Jamie Reynolds from Klaxons.

After the group knocked back hundreds of pounds worth of cocktails, the karaoke machine kicked in and, as if on cue...

The X Factor judge Louis Walsh and Simon Cowell’s girlfriend Terri Seymour ¬arrived just as the singing started.

Nick and Jaime, 23, serenaded the crowd with some of Elton John and Amy Winehouse’s back catalogue, before Nick was handed a birthday cake by Jaime.

But Louis left looking unimpressed and it all seemed a bit much for model-of-the-moment Alice Dellal, who, after perhaps one too many vodkas, took a tumble as she checked out the giant plant pots in the smoking area.

But she pushed on through with the help of Jaime who, after the karaoke session ended at 4am, dragged the gang to Tottenham Court Road for an after party until 8am at The Spanish Bar.

That’s some serious party stamina  – theBuzz salutes you!
