Gossip Girl stars Blake Lively and Penn Badgley are trying to be funny in a pro-Barack Obama commercial that jokingly warns of the dangers of voting for John McCain. But still, it’s true. Vote McCain at your risk.

Here she is outside the David Letterman show without any pants on showing off her long sexy legs. I hope this becomes a new trend. Cuz this is how I picture her walking around my place…In my dreams of course.
