Talent agent Renee Tab, who was involved in a physical altercation with Sharon Osbourne in early April, has fired back with new details about the incident at the Koi restaurant in Los Angeles that has resulted in each woman alleging to police that the other assaulted her.Tab's lawyer, Najila Brent, has told New York Daily News that, on the night in question, Sharon confronted Tab about the $15,000 necklace that Osbourne has claimed Tab absconded with after crashing her New Year's Eve party. Tab has maintained she won the raffle prize fair and square. According to Brent, Tab said, "Are you here to apologize to me?" Brent said that Osbourne "started screaming racial slurs - 'You Persian carpet cleaner! You Iranian [bleep]!'" The lawyer, who says she will be adding civil-rights charges to the suit Tab plans to file, claims Osbourne kicked Tab and her sister, Candace, and "spat three or four times on Renee." Brent also contended that Sharon told Tab, "I'm going to send someone to slash your face and break your leg." "Renee is afraid for her life right now," said Brent, who is seeking a restraining order against Osbourne. She added that doctors have told Tab she suffered a concussion in the melee. Osbourne rep Lisa Vega responded that Tab and her lawyer "live in a fantasy world. Sharon is the one with the injuries. She's going to file her own charges."
