Sharon Osbourne Attacks Jonah Hill's Brother

Sharon Osbourne attacks Jonah Hill's brother Jordan Feldstein at Clive Davis' pre-Grammy party.

Whatever went down between Sharon Osbourne and Jonah Hill's brother Jordan Feldstein was enough to drive Osbourne to explode at him, and some innocent food was the casualty.

At Clive Davis' and The Recording Academy's pre-Grammy gala at the Beverly Hilton Hotel on Saturday (Jan. 25), "The Talk" host got into an extreme argument with Maroon 5's manager (while his brother was in NYC hosting "Saturday Night Live"), E! News reports.

So what set off the rock 'n' roll mom? According to a source at the party, daughter Kelly Osbourne was seen arguing with Feldstein at his table during dinner. "There was a lot of finger pointing," an eyewitness says.

Kelly then walked away from Feldstein and Sharon showed up at the table. "The arguing continued," the source says. "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."

While we don't know what exactly they were all arguing about, the lesson here is clear: Never get into a fight with an Osbourne (and apologies to Sara Bareilles, who was just an innocent bystander sitting at the table during the blow-up).

Hill's brother Feldstein gained some notoriety of his own in November when he married Clint Eastwood's daughter Francesca Eastwood in Las Vegas. The quickie marriage was annulled about a week later.
