Etta James on Obama: "He Ain't My President"...Says Beyonce "Gonna Ger Her Ass Whooped"

This report reveals some shocking audio. This has to be the most magnificent moment in music since the debut of Men Without Hats.

71-year-old Etta James actually threatened to beat the crap out of Beyonce Knowles -- and it's caught all on tape!

The war is all over Etta's song, "At Last " -- Beyonce sang the tune at Obama's 1st Inauguration Ball on Jan. 20th ... but last week at a concert in Seattle, James was still pissed.

While on stage, Etta told the crowd, "Your President, the one with the big ears ... he had that woman singing my song. She gone get her ass whipped."

She continued, "The great Beyonce ... I can't stand Beyonce."

Ironically Etta didn't kick up this sorta fuss when Beyoncé portrayed her in "Cadillac Records."

Reps for Beyonce had no comment.

Here's the shocking audio.



You go girl! And sing it one more time.
