The actor was spotted once Sunday taking photographs and again Wednesday marching and holding a sign stating “Bring Back The Glass Stengell Act!! No To Corporate Greed!” according to The Huffington Post.

“I mean, listen, it’s cheesy… but I want to do whatever I can,” the actor said to Capital NY on joining the protests after a friend was arrested on the Brooklyn Bridge.  “It’s absurd that celebrity power is what it is…use any tool you have, you know?”

The 24-year-old Gossip Girl star joined demonstrators at New York City’s Occupy Wall Street protests, being the latest liberal-leaning celebrity to join the nationwide movement.

The Occupy Wall Street Movement, a populist sit-in demonstration against the corruption of the financial industry, is uniting people nationwide.

While The Huffington Post states that the movement represents those not making millions a year, the other 99 percent of the nation, it has gained attention and support from numerous actors and entertainers.

Other celebrities who have joined the movement include Mark Ruffalo, Michael Moore, Lupe Fiasco, Susan Sarandon and Tim Robbins.
