The British actress was photographed using walking aides while promoting her new film, Terminator Genisys, in London recently, and now she has revealed the reason why, admitting the accident which led to her injury was the result of her own clumsiness.

She tells BBC Radio 1, "I've got a stress fracture on my hip. I want to say it's from Parkour (urban obstacle course) or something - something really brilliant, like I'm trying to vault a wall - but, in reality, I just slipped. It's really boring."
