Today is Joan Crawford's birthday. Which one? Well, we're not quite sure—depending on the source she was either born in 1905, 1906 or even 1908. Of course it doesn't really matter—Joan was timeless.

If you're in a mood to celebrate, you can turn on Turner Classic Movies—they're running her films all day—or download Mommie Dearest on iTunes. (Sorry, it's no longer on Netflix streaming.)

If you're short on time, though, watch this terrific tribute to the Oscar winner, set to the tune of Stephen Sondheim's "I'm Still Here." (Not only was it Sondheim's birthday yesterday, but legend has it he wrote it with her in mind.)
