Kelly Clarkson is once again at odds with RCA Records. This time the dispute is over her new power ballad — which sounds bizarrely like Beyonce’s 2008 hit, “Halo.”

The dispute began after the American Idol Season One champ realized that “Already Gone,” a tune she co-wrote with hit songwriter Ryan Tedder, was a deadringer for another Tedder-penned tune, “Halo.”

Tedder recently confessed that he gave both platinum-selling singers a tune with the same backing track. However, by the time Kelly heard “Halo” and realized the similarities between the tracks, it was too late to make changes to her current album, All I Ever Wanted, which debut last spring.

In an interview with Canada’s CBC Radio this week, Kelly reveals that she has been fighting behind the scenes to keep her latest single, “Already Gone,” from being released — to no avail.

“No one’s gonna be sittin’ at home, thinking ‘Man, Ryan Tedder gave Beyoncé and Kelly the same track to write to.’” she said. “No, they’re just gonna be saying I ripped someone off.”

A frustrated Kelly adds, “I fought and fought” to stop it, she said, but couldn’t. “In the end, they’re releasing it without my consent. …It sucks, but it’s one of those things I have no control over. I already made my album. At this point, the record company can do whatever they want with it. It’s kind of a sh- – -y situation, but . . . you know, you learn.”
