More than 2 million fans attend free Lady Gaga concert in Rio de Janeiro

Lady Gaga gave a free concert Saturday night in front of more than 2 million fans, who poured onto Copacabana Beach in Rio de Janeiro for the biggest show of her career.

"Tonight, we're making history," Lady Gage told a screaming crowd. "Thank you for making history with me."

The Mother Monster, as she is known, kicked off the show just after 10 p.m. local time with her 2011 song "Bloody Mary." Cries of joy rose from the tightly-packed fans who sang and danced shoulder-to-shoulder on the vast stretch of sand.
