Ben H. alerts us that Natalie Portman will be on Late Show with David Letterman tonight 11:35 EST and Ewan McGregor will be on Tonight Show with Jay Leno tonight 11:35 EST.

Update: Gabe reports:

I just saw both Jay Leno and David Letterman tonight with Ewan McGregor and Natalie Portman, respectively.

Ewan was great, telling a really funny story about him appearing nude on stage. He and Jay also spoke about Ewan's uncle who played Wedge in the original trilogy. He said that his uncle told him not to appear in the new trilogy unless he didn't want to have a career after he was thirty. Interesting. Overall, it was a very funny appearance. He looked pretty enthusiastic about the film.

Natalie Portman's appearing on David Letterman was nothing short of jaw dropping. She came on stage wearing long black dress that was very low cut on the front. Very, very sexy.
