One Direction hunk Harry Styles has confessed he was "in stitches" when a stripper gave him a birthday lap dance.

The international superstar partied the night away with friends in East London haunts The Alibi and Rita's Bar and Grill on Friday night.

Styles - who was celebrating turning 19 - was treated to a lap dance from his pals by an underwear-clad girl during the festivities.

A series of pictures from the raucous revelry were posted by a fan on Twitter, and now Styles has revealed all about his cheeky birthday celebrations.

He told The Sun; “I was in stitches, it was really funny. We had a great night.

“She stripped down to her underwear but unfortunately there was a no-nudity policy in the bar. She didn’t handcuff me but the funniest part was that when she finished she said, ‘I’m really sorry I couldn’t find my truncheon so I had to bring my nunchucks’. That was a bit weird.

“Then a guy in our group came up and said, ‘I went to college with her!’ ”

Styles revealed it was Radio One DJ Nick Grimshaw who planned the birthday surprise.

He added: “Grimmy said I had to sit there because he was bringing a cake. He started telling everyone to be quiet but I could see the cake in the kitchen and the candles weren’t lit, so I was like, ‘What’s going on?’ Then Grimmy said, ‘Someone in here is under-age’ and I saw a police hat bobbing through the crowd. I was like, ‘Oh no!’

“The stripper didn’t really say anything, she just began her routine. I have never seen my manager run so quick to cover the CCTV cameras but the pictures got out anyway.”
