Because He’s Hot: Robert Pattinson Arrives at David Letterman (PHOTOS)

Twilight's R-Rated Sex?
Bill Condon jokes it's Kristen's fault!
Robert Pattinson arrived in style for his appearance on David Letterman Tuesday afternoon. Looking smoldering in a blue on blue shirt and jacket, Rob wasted no time before he went to greet his fans who had been waiting outside the Ed Sullivan Theater for several hours.

Rob has been his charming self while hitting the talk show circuit to promote Breaking Dawn Pt. 1 so we can’t wait to see what he has in store for us tonight.

Apparently, Pattinson talks about why he started acting (to meet girls), his older fan base, and the new film.

Photographer Annie Leibovitz will also be on Tuesday night with musical guests David Crosby and Graham Nash.
