50 and fabulous! That's right--Diane Lane, who remains positively radiant, is ringing in her 50th birthday today. The actress, who began acting on-stage at the age of six, eventually transitioned to big screen productions, acting in Jumper, Man of Steel, and the wildly popular Unfaithful, which earned her an Oscar nod back in 2003. Next up? The actress is lending her voice to the highly anticipated animated feature Inside Out, fronted by Amy Poehler, Mindy Kaling, Bill Hader, and more. In honor of the star's birthday, we're taking a look at more stars who have also celebrated the big 5-0.
