Carter: Osbourne biggest brat of all

Aaron Carter has hit back at Jack Osbourne's comments he could beat him up and has branded the 20-year-old star a "brat".

The feud was recently ignited when Osbourne criticised 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" Carter.

However 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."
