According to the report, Stiviano was leaving a Manhattan restaurant when two men approached her and "punched her on the right side of her face several times," her lawyer Mac Nehorary said.
The incident was originally reported by Radar Online and that report included several more details. When asked by NBC if the Radar Online report was accurate, Nehorary told NBC, "The story is true."
Among the details in the Radar Online report:
• The attackers were "two white men" — “They were about 5 feet 7 and they knew exactly who she was," Nehorary said.
• Along with punching Stiviano, Nehorary said the two men called her the N-word and used "other disgusting slurs."
• After Stiviano managed to run away, "several onlookers then began attempting to apprehend the two men."
• Stiviano was taken do a doctor and, despite having an "extremely red" face and being scared, she is expected to make a full recovery.
• Stiviano had not yet filed a police report, but "will probably do so."
Radar Online added that Stiviano was in New York to appear with Nehorary on CNN's "Anderson Cooper 360" on Monday. Despite the attack, Stiviano still plans to be on the show.
"No one will intimidate her," Nehorary told Radar Online.
The incident was the latest in a bizarre Sunday in which TMZ revealed a video purportedly from 2011 and showing Stiviano making racist comments, and Sterling spent the day at a predominantly black church in Los Angeles.
Last Thursday, Shelly Sterling on behalf of the Sterling family trust signed into an agreement with former Microsoft CEO Steve Ballmer to sell the Clippers to Ballmer for $2 billion. Shelly Sterling was reportedly able to bypass Donald's approval because he was reportedly declared mentally incapacitated — there is language in the trust which gives Shelly sole authority to make the sale if such a diagnosis is made. All that remains for Ballmer to assume ownership is approval of the other NBA owners.
Sterling has since sued the NBA and commissioner Adam Silver for more than $1 billion.
A national firestorm was set off last month at the beginning of the NBA postseason after recordings surfaced of Sterling making racist comments to Stiviano. Silver took prompt action, banning Sterling for life, fining him $2.5 million and recommending the league's owners force Sterling to sell the team.
