Kristen Stewart Drops By David Letterman

While her co-star Robert Pattinson was busy chatting it up on the "Tyra Banks Show," Kristen Stewart was spotted readying for an appearance on the "Late Show with David Letterman" in New York City on Thursday evening (November 20).

The 18-year-old rising star was on-hand promoting her brand new movie "Twilight" - a much-anticipated vampire flick opening up in theaters tomorrow (November 21).

Meanwhile, Stewart, who plays Bella Swan in the book-based film, recently talked about how she thinks her co-star Pattinson is definitely "pretty sexy."

"Oh, he's like a little tortured artist. He's British. He's tall," Stewart told People magazine. "He always looks like he's thinking about something. And he's quite witty. So he's pretty sexy."
