Lady Gaga Urges Fans To Protest Arizona Immigration Law (VIDEO)

Lady Gaga rallied fans to protest the Arizona immigration bill during her concert in Phoenix Saturday night.

"We have to be active," she told the crowd. "We have to actively protest. I will not cancel my show. I will hold you, and we will hold each other, and we will protest this state."

Gaga had "Stop SB 1070" written on her arm and said that she had gotten "a phone call from a couple really big rock and rollers, big pop stars, big rap artists" asking her to boycott Arizona.

"I told them, 'Do you really think that us dumb [expletive] pop stars are going to shut down the state?'" she said.
