How old is Jane Fonda? Would you believe 73?

Would you believe she turned 73 in December? Us either. Sure, she was a bombshell in "Barbarella" and "Klute," but she has also aged incredibly well, especially considering she's overcome breast cancer and had a hip replacement. And she doesn't look like she's had to much work done, which is nice.

She joked about being called a "cougar" backstage and cracked, "Young man, I don't even know what that means. So would you please put your clothes on and get out of my dressing room?" Jane also recently joked with Ellen DeGeneres about her septuagenarian sex life. So good for her!

Fonda hasn't been onscreen since 2007's "Georgia Rule," but she can be seen in the upcoming "Peace, Love, & Misunderstanding," in which she plays a hippie Grandma to Jeffrey Dean Morgan's children played by Chace Crawford and Elizabeth Olsen (younger sister to the Olsen twins). Sounds fun.
