Jim Carrey — Celebrities Who Turned 50 in 2012

So, what's funnyman Jim Carrey up to now that he's part of the 50 crowd?

Well, let's see -- he's wrapped up production for 'Kick-Ass 2: Balls to the Wall' where he plays Colonel Stars and Stripes, there's talk of him starring in 'Dumb and Dumber 2' with Jeff Daniels, and there's photo evidence that suggests he snuck in a cameo appearance in 'The Walking Dead.'

Just kidding about that last part, but he's certainly not acting like he's 50! Actually, he's going to turn 51 come January 17, so perhaps the hype has already died down.
