What’s all this about water throwing and food fighting? Jonah Hill and his brother at the Grammys and Sharon Osbourne?

Clive Davis’ pre-Grammy party in Los Angeles set the stage for a spat between TV personality / legendary rocker wife Sharon Osbourne and manager / brother of Jonah Hill, Jordan Feldstein. Apparently, there has been a longstanding feud between Feldstein and Sharon’s daughter, Kelly. Sharon decided to step in. That’s when things got real.

With all the positive publicity and rave reviews Jonah has been receiving post Oscar nom and SNL hosting gig, it seems a shame that his brother would rain on his parade. According to E! News, “They were going back and forth and then all of a sudden, food was flipped onto Jordon. He got up to walk away and then Sharon threw a glass of water at him.”

Jordan Feldstein and Kelly Osbourne have had some major tension going on between them in the past, though the reason for the longstanding feud is still unknown to most. Both Kelly and Jordan (along with Jonah) grew up in West Los Angeles, so perhaps the feud hearkens as far back to high school days. According to an onlooker, Feldstein and Kelly got into a spat when mother, Sharon decided to get involved.

Feldstein, who also manages Maroon 5, made news when he married Clint Eastwood’s daughter Francesca Eastwood in Vegas, back in November. According to The San Jose Mercury News, the wedding was annulled a week later.

Jonah Hill has a lot more on his plate than a little sparring match between his brother and the Queen Bee Osbourne. He’s got an Oscar outfit to plan…a speech to prepare…wait, maybe we’re getting a little too carried away. You get the idea.

With his outstanding performance in Wolf of Wall Street, and his incredible return as three-time host on SNL, Jonah Hill is on his way to becoming one of the biggest names in Hollywood.

Whenever he needs a boost, he can always call on his pal Leo for a little Titanic re-enactment.
