Hollywood star Jim Carrey broke a rib on the set of new movie Yes Man, after falling over during a scene with co-star Molly Sims. Sims reveals the funnyman was so full of energy and enthusiasm during the shoot - in which he plays a man who bans himself from saying 'no' - he ended up with a painful injury.

She says, "Jim broke a rib. A scene called for us to bump into each other, and he just went for it and crashed around and broke a rib for real. He's a trooper though - he finished the scene."

Meanwhile Sims was left astonished by Carrey's nonstop sense of humor - and struggled to get through serious scenes with a straight face.

She adds, "My insides of my mouth were raw from biting my cheeks to stay in character, and not laugh out loud."
