Hollywood agent Renee Tab, accused of belting Sharon Osbourne on the chin and leaving a bruise that Osbourne displayed Tuesday on TV's "Celebrity Justice," slapped back Wednesday with her own version of the reputed catfight.

The two women have been feuding over a $15,000 diamond necklace that Tab -- whom Sharon called an uninvited guest -- won as a door prize at a New Year's Eve party thrown by the Osbournes.

Tab, 26, who works for International Creative Management, said Wednesday that Osbourne spat at her after "terrorizing and harassing" her for three months, reports Reuters.

"It is Mrs. Osbourne who viciously, verbally and physically attacked and spat upon Renee Tab and her sister," said a statement issued by her lawyer.

The statement threatened legal action against Osbourne both over the attack and "her defamatory statements."

The two women confronted each other in a West Hollywood Japanese restaurant last Thursday. Bruises ensued. Police, saying that each of the women had filed complaints of battery against the other, are still probing the matter to determine if charges should be filed.

"I honestly thought my jaw was broken," Osbourne, 50, said on TV earlier this week. "I've got a bruise on my chin. It hurts. My ears hurt. My neck hurts. My teeth have to be redone."
