Sara Bareilles refuses to become mired in drama. The 'Brave' singer has fired her manager Jordan Feldstein, the older brother of actor Jonah Hill, after he engaged in a fight with Sharon Osbourne at a pre-Grammy fete. The matriarch was so incensed that she threw a plate of food at Feldstein.


The following day, Bareilles gave her manager the boot. Feldstein is not pictured in the photo above, where Mama O. is clearly heated.

Feldstein's roster includes the multi-platinum likes of Robin Thicke and Maroon 5. He found himself in the headlines for his quickie marriage to Clint Eastwood's daughter Francesca, which was on its way to being annulled.

So WTF happened to set Sharon off and to cause Sara to axe him?

He and Sharon O. battled at Clive Davis' party (Jan. 25) at the Beverly Hilton.

He was first seen engaged in an argument with Kelly Osbourne in the ballroom. Kelly then stormed away from his table and Sharon picked up where Kelly left off.

A witness told The Hollywood Reporter that "Sharon walked up to him pointing her finger and screaming." The exchange escalated and Osbourne threw food in his lap and poured water over his head. Bareilles was seated nearby, as was Taylor Swift.

What caused the fight? Apparently, Feldstein made comments about Sharon's son Jack and his wife. The exact nature of those comments remains a mystery, but they were apparently unsavory enough to get Kelly and Sharon going and ultimately lead to his dismissal by a cred client. We don't know Feldstein's side of the story yet, but things had to be pretty bad all around to cause food to be thrown and a client to fire him.
