Beyonce kicked off the US leg of her international solo tour 'I Am' as alter-ego Sasha Fierce in Madison Square Garden in New York on Sunday night. Husband Jay-Z made a cameo to help her sing the show's opener, 'Crazy In Love.'
The singer was supposed to perform on Saturday at New York's M2 nightclub but backed out because she said she was too busy. Club owner Joey Morrissey is threatening a million-dollar lawsuit; Beyonce's label says she never had a contract with the club.
