Kate Beckinsale, who turned 39 today, made a guest appearance on Conan on Wednesday evening to promote her new movie, ‘Total Recall’.

The British actress plays one of the central villains in the movie, but it almost wasn’t to be.

Apparently, the actress was originally the front runner to play the three-breasted woman (played by Kaitlyn Leeb).

Of course, that was the main topic of conversation.

The British actress wore a Thomas Wylde Spring 2012 dress for the occasion.

Her form-fitting LBD with ruffled details was styled with J/Hadley earrings and Rona Pfeiffer rings.

I’m positive she wore this dress with black pumps with this look.

Kate’s co-star Jessica Biel, was also doing the TV rounds last night on Jay Leno.

I can’t wait to see the both ladies on the red carpet next week at the LA premiere.
