Brad Pitt will be walking with a cane for a while, thanks to a knee injury – but it didn’t occur on the set of a stunt-heavy movie.

Instead, Pitt hurt himself parenting. “I was carrying my daughter (Vivienne) down the hill and I slipped,” Pitt says, according to People magazine. “It was either her or me.”

It’s a good thing that Angelina Jolie is a fan of the new accessory: “I like the cane,” she says, adding that the limp hasn’t done much to slow Pitt down. “He’s not that kind of guy. He does everything still.”
