Penn Badgley doesn't only care about the Upper East Side!

The 24-year-old Gossip Girl star marched amongst demonstrators Wednesday morning as a part of NYC's Occupy Wall Street protest.

Zoe Kravitz's new beau told Capital NY that he came to the protests in Zuccoti Park after a friend was arrested on the Brooklyn Bridge. "I mean, listen, it's cheesy," he said. "But I want to do whatever I can. Let's be honest: I'm on f**king Gossip Girl... It's absurd that celebrity power is what it is, but, like, use any tool you have, you know?"

Badgley isn't the only star to join in the march against corporate greed. Susan Sarandon, Michael Moore, Mark Ruffalo, Russell Simmons and Tim Robbins have all participated in the protest as well.
