Aaron Carter: "Jack Osbourne the Biggest Brat of Them All"  11/6/06

Aaron Carter has hit back at Jack Osbourne's comments he could "kick the s**t out of him", and has branded the 20-year-old star a "brat".

The feud was recently ignited when Osbourne criticized Carter for "pretending to be black" in new reality TV show House of Carters, and admitted he would gladly start a fight with "irritating little b**tard" Carter.

But Carter has dismissed Osbourne's claims he could beat him up.

He says, "He's welcome to try to kick the s**t out of me any time he likes. I normally love Brits but this guy's brain-dead. He comes across as the biggest brat of them all on his show."

Brother Nick Carter adds, "What Jack Osbourne knows about talent would barely fit on a postage stamp."
