Harry Styles rumbled James Corden when the actor tried to prank his friend on Michael McIntyre's chat show.
Former Gavin And Stacey star James sent the One Direction heartthrob a text with the message : "Me and you, lapdancing. Are you in or out? Come on, let's do this."
Harry played along at first, replying: "Great, but what is it with you and lapdancing? What happened the last time we did that wasn't pretty."
But when he joked of James's young son: "Maybe we shouldn't bring Max this time," Harry showed that he knew that he was being pranked, before adding: "Are you playing send-to-all with Michael McIntyre?"
Harry was the victim of a phone prank in March, when he agreed to lend £5,000 in cash to Matt Healy from boy band The 1975, despite hardly knowing him.
Matt called him up while playing the Call or Delete game on Nick Grimshaw's BBC Radio One breakfast show.
