James is reportedly heard blasting Beyonce Knowles for singing a version of her song "At Last" for President Barack Obama after his Inauguration last month, reports TMZ.com.

Knowles, who portrays James in new movie Cadillac Records, belted out the blues icon's most famous tune as Obama and his wife, Michelle, shared their first dance at the Neighborhood Ball in Washington, D.C.

In the audio -- reportedly recorded at an Etta James concert in Seattle, Washington on Jan. 28 -- a woman said to be the 60s legend is heard mocking Obama's looks and slamming Beyonce's performance.

The woman apparently tells the audience, "You guys know your President right? You know the one with the big ears. Yeah, wait a minute, he ain't my President, he might be yours."

The voice in the audio goes on to say, "I tell you that woman he had singing for him, singing my song, she gonna get her ass whipped. The great Beyonce! I can't stand Beyonce! She had no business up there singing... Singing my song that I've been singing forever."

Last month, James' son Donto told the New York Daily News his mother had watched the performance live on TV at home in California, and was delighted her love song had become a part of history.

He said, "She was looking forward to seeing it. She was honored (and) she thought it was great. She's gotten emotional, just like everybody else."
