Tom Cruise and Matt Damon reportedly got spanked in a London nightclub this week.
The actors were at The Box celebrating Matt's 42nd birthday, and ended up getting "paddled" on the bum by a transvestite hostess.
Speaking to the New York Post, a source said: "They all had a fantastic night enjoying the shows and partying until the end."
Tom apparently arrived on his own but soon got stuck into the party spirit and was happy to receive some punishment.
The insider added that Matt got "some extra spanking" because he was the birthday boy.
Other screen stars at his wild bash included Chris Hemsworth and Emily Blunt.
Emily's husband John Krasinski was the mastermind behind the party and we have to say, it sounds like a pretty fun idea.
Tom, Emily and Bill are currently in London shooting new sci-fi flick All You Need Is Kill.
We wish we could have been there to witness it all!
How much would you want to see a video of the guys getting 'punished'?
