According to The Arizona Republic, Gaga blasted the law during her Arizona show recently. She said: "We have to be active, 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, who had Stop SB 1070 written on her forearm at the gig, added: "I got a call from some big rappers and big rockers, they said, 'We'd like you to boycott Arizona because of SB 1070'.

"I told them, 'Do you really think that us ... pop stars are going to shut down the state?'"

The Pop star also took to her Twitter page to protest against the bill.

She wrote: "Tonight we will continue to actively protest social and political injustices in Arizona. We will sing, we will stand up, + we will be heard."
