Nicky is working hard on expanding her brand. First she conquered handbags (they're huge overseas), then went on to produce her Chick clothing line and now she is pimping her upcoming hotel on Letterman. Yes, the interview is slightly awkward. You would think Dave would not be into the Hilton's however, like most men in America he seems somewhat smitten with them. He's always super sweet to Paris when she is on the show.

I think she not only keeps her cool on Letterman, but she looks pretty cute at this Saks charity event.

Lots more pics of Nicky so read more
