(Cover) - EN Showbiz - Josh Duhamel sprained both his ankles in one day while shooting Transformers: Dark of the Moon.

The actor has reprised his role as Major William Lennox for the third instalment of the sci-fi franchise and has previously admitted he loved getting involved with some of the stunts. Unfortunately for Josh he's very clumsy, meaning he was regularly injured on set.

"I actually got a little bit hurt this time, not because it was dangerous, but because I'm a klutz. I sprained one of my ankles before lunch and then after lunch I sprained the other," he admitted.

"I'm not kidding you. I sprained not one, but two ankles in the same day. My nickname became H.R. Stumblesnstuf."

Josh has been married to Black Eyed Peas singer Fergie for two years. Ever since they tied the knot people have been expecting them to start a family, and while they would love kids they aren't planning on having any for a while yet.

Josh is content to play with his niece and nephew who are twins and a handful.

"They're two and they are at the perfect age," he told E! Online. "They're just hilarious. But you also have to learn what's good about your house for kids and what isn't. They don't always mesh, and kids will find the most dangerous places." (C) Cover Media
