Sharon OsbourneSharon OsbourneSurely a show hosted by Jerry Springer is guaranteed to be mired in controversy from the get-go?

No surprise then, that feisty femme Sharon Osbourne has been fuming, flouncing and fighting with fellow judge, Piers Morgan on America's Got Talent.

Sharon, who judges on the show alongside Piers and David Hasselhoff, has stormed off the programme's set.

So what's the reason behind Sharon throwing her toys out of the cot?

Piers ridiculed a nine year old contestant on the show.

Outraged, she ripped up her notepad and stormed off, shouting: "I've had it."

The sentimental wife of rocker Ozzy, is famed for giving Simon Cowell a piece of her mind on The X Factor, and for crying about acts she didn't like sending home.

But for once, Simon agrees with Shazza on the row:

"He (Piers) is actually very annoying and somebody has to tell him that."
