“Gossip Girl” actor Penn Badgley was spotted by a Gawker tipster Wednesday marching with demonstrators to City Hall and holding a sign that said, “Bring Back the Glass-Stegall Act!! No to Corporate Greed!”

The actor told Capital NY that he came to the protests after a friend was arrested on the Brooklyn Bridge “I mean, listen, it’s cheesy ... but I want to do whatever I can,” he said of his participation. “Let’s be honest: I’m on [expletive] ‘Gossip Girl.’ So, why not try and ... right? It’s absurd that celebrity power is what it is, but, like, use any tool you have, you know?”

Perhaps following the lead of his former partner, Susan Sarandon, Tim Robbins stopped by the protests Wednesday. He told the Financial Times (via People), “This is what an actual grassroots movement looks like. ... It’s a bit sloppy and disorganized but full of passion.”

Yoko Ono voiced her support on Twitter: “I love #OccupyWallStreet. As John said, ‘One hero cannot do it. Each one of us have to be heroes.’ And you are. Thank you.”

Michael Moore and Mark Ruffalo also count themselves among the 99 percent.
