So who better to give the Biebs some advice on hitting the London scene than the Brit boybanders from The Wanted?
"Watch out for loose women," Max George told E! at last night's Stars & Strikes Celebrity Bowling & Poker Tournament. "There's a lot of them in England."
Meanwhile, Jay McGuiness had some tips on dealing with the U.K. paparazzi. "Keep your head down, keep walking," he said.
"Security," Siva Kaneswaran added. "Bring security."
There you have it, Biebs: Watch for women and keep calm around paps!
