One Direction's Harry Styles Gets Birthday Stripper
Pals surprise Harry with lapdancer dressed as policewoman...
And Niall revealed via Twitter that Harry was not his usual smooth self with the saucy pretend policewoman.
He wrote that his pal was ""so shocked" and that he'd "never seen him so scared before".
The group later went on to east London nightclub Alibi - where they partied until around 4.30am.
Harry celebrated with old flame Caroline Flack and other friends earlier in the week.
