Soul veteran Etta James has apparently had enough of Beyoncé Know­les stealing her act. Knowles portrayed James in the film Cadillac Records and performed James’ classic hit At Last for Barack Obama at an inauguration ball for the U.S. president.

But now James is hitting back. “You know that woman he had singing for him, singing my song — she’s gonna get her ass whooped,” James said at a Seattle concert, according to Perez Hilton. “I can’t stand Beyoncé. She has no business up there.”
