Sharon O In Food Fight With Jonah Hill's Brother

Sharon Osbourne is reported to have become involved in a food fight with the brother of actor Jonah Hill at a pre-Grammy Awards party.

The TV personality is claimed by E! News to have thrown a glass of water over music manager Jordan Feldstein at Clive Davis and The Recording Academy's pre-Grammy gala.

The annual event is the highest-profile pre-Grammys event in town and the disturbance apparently began during the early dinner portion of the evening.

Feldstein is claimed to have become involved in a row with Kelly Osbourne, with a witness quoted as saying: "There was a lot of finger pointing."

Kelly-O apparently then walked away but was replaced by Shazza.

"They were going back and forth and then all of sudden, food was flipped onto Jordan. He got up to walk away and then Sharon threw a glass of water at him."

Another source told E! that the Osbournes have a "long-running feud" with Feldstein.
