Damian is actress Elizabeth's only child, from her brief relationship with American businessman Steve Bing back in 2001. It seems as if the teenager is set to follow in his mum's footsteps; he recently made his acting debut in Elizabeth's drama series The Royals, joining his mother on screen in the role of Prince Hansel.

Appearing on ITV's Lorraine last year, she explained: He loves being there [on set]. We shoot right across the summer holidays so actually there's not a lot of choice in that but thank goodness he enjoys it even more than I do. So he sets my alarm every morning, he gets out my clothes for me, he runs my lines with me, he bullies me all day long." She added: "I don't know if he will be an actor. I think he will be in showbusiness. He might be behind the camera. He's quite despotic when he’s making his own little mini movies, he’s quite good at it. I think he wants to run a studio, maybe employ his aging geriatric mother. We'll see you, never know."
