Working those famous long legs in a super short skirt, Cameron Diaz stepped out for a guest appearance on “The Tonight Show” on Tuesday night to talk to Jay Leno about her new movie “What To Expect When You’re Expecting”.

Cameron wore a silk black blouse and flounce skirt from the Fall 2012 collection by Stella McCartney.

During her chat with Jay, the 39-year-old actress dished on her impending 40th birthday and how she ‘burst into tears’ when her friend recently cut too much length off of her hair.

I loved this studded skirt on the runway, though I originally thought it was part of a dress.

Cam finished her look with gold jewelry from Pomellato and Eddie Borgo and a pair of Lanvin sandals.
