Harry Styles saw the funny side of his birthday stripper, and the One Direction star admitted he was "in stitches" when the brunette - dressed as a policewoman - had forgotten her truncheon.The One Direction heart-throb was given the curvy brunette as a gift for his 19th birthday on Friday (03.02.13), and he saw the funny side when the stripper - dressed as a police woman - had forgotten her truncheon.Talking to The Sun newspaper, he admitted: "It was great. I was in stitches ... 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."The 'Little Things' hitmaker was celebrating his birthday at The Alibi in Dalston, East London with his friends, and Radio 1 DJ Nick 'Grimmy' Grimshaw set up the surprise.Harry revealed: "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."
