Actor Tom Cruise’s derriere is “quite real”, says one of his co-stars amid speculation that he had used some form of prosthetic to give his backside a boost on the set of his Second World War hit Valkyrie.

Annabelle Wallis, who starred alongside Cruise in The Mummy, told TMZ: “I think it’s all quite real.”

She also said it’s true that the actor saved her life while filming The Mummy when something got wrapped around her neck during a stunt.

Cruise has already debunked the “fake butt” rumours earlier this week.
