Gossip Girl star Leighton Meester stopped by The Late Show with David Letterman on Friday night, and she was as funny and wonderful as you'd expect.

In addition to debunking Letterman's misconception that her character is the voice of Gossip Girl (he should really tune in), Leighton also talked about ...

• How she was recently pulled over for speeding while covered in fake blood from a movie she was making over the summer.
• How her dog looks and acts like actor Richard Gere (with pics)!
• How there's a lot of sex, partying and clothes in Season 3.

Check out Leighton's interview below ...
