Music legend Etta James has blasted fellow diva Beyonce for singing her signature song “At Last” to Barack Obama at one of the presidential inaugural balls. “I tell you, that woman he has singing for him, singing my song, she gonna get her ass whipped,” James told concert-goers in Seattle on Jan. 28. “I can’t stand Beyonce, she had no business up there singing … my song that I’ve been singing forever.” The fight seems odd given that Beyonce recently portrayed James in the movie Cadillac Records, in which she sang “At Last,” among other songs.
