Natalie Portman Talks Etiquette and Horseback Riding

Natalie Portman is still rolling solo out promoting The Other Boleyn Girl. Seriously, what did Scarlett do to get out of this leg of the tour? Nat stopped by Letterman last night to talk about horseback riding and how hard it was to go to the bathroom when she was in costume — good times, check out the video after the jump. Even more exciting, however, is that my overseas counterpart PopSugar UK got to see Natalie, Scarlett and Eric Bana in person and quiz them a little about the movie. Check out the first installment of her interview here (with much more to come!). How fun!
