Kanye West and Russell Simmons caused a stir in New York City on Monday when they joined demonstrators at the Occupy Wall Street protest in Zuccotti Park.

According to The FW, West and Simmons stopped by the news-making gathering yesterday afternoon, but their appearance was brief. The two hip-hop stars soon got in a car and left the scene.

"I just walked @kanyewest thru the #occupywallstreet," Simmons tweeted. "I love how sweet and tolerant he was to the crowd." The mogul also posted photos of his and West's appearance on Twitter and his site, Global Grind.

Simmons continued to tweet about West's Occupy Wall Street cameo, applauding him for "using his celebrity to help others," and saying that it was "inspiring to others to see him there." On Tuesday, he added, "Its tough being @kanyewest people were climbing on him. it was a huge security risk but he just kept shaking hands #occupywallstreet."

This isn't Simmons' first appearance at the ongoing NYC protest. He's been supporting the group's cause for a while, and recently told CBS News that he's "happy to pay more taxes." He added, "I come because I love their intention and their effort and their courage. I'm just a big supporter of what these young people are doing. They want the money out of Wall Street, they want the power to the people. It's an old chant."
