But Stiviano appears not to have any hard feelings with Rochelle Sterling.
Speaking with KTLA News and other news organizations Friday, she said: "I love Mrs. Sterling."
She made the comments as she walked into her home near Beverly Center, chatting with reporters about issues ranging from fashion to hot chocolate.
Nearly 50 years Sterling's junior, Stiviano was sued last month by Rochelle Sterling, who seeks the return of the duplex as well as a Ferrari, two Bentleys and a Range Rover she said her husband bought for Stiviano.
Rochelle Sterling alleges in the lawsuit that her husband met Stiviano at the 2010 Super Bowl in Miami. The suit describes Stiviano, 31, as a seductress who targets wealthy older men like the 80-year-old Sterling.
According to property records, Stiviano purchased the duplex in December 2013. But Rochelle Sterling says that she allowed her husband to pay for the house, believing that her name would be on the deed along with his.
Sterling also gave Stiviano $240,000 for living expenses, according to Rochelle Sterling's lawsuit, amounting to $2 million of community property that he allegedly spent on Stiviano without his wife's knowledge.
In a response to the lawsuit, Stiviano argues that Rochelle Sterling must have known that her husband of more than 50 years had romantic relationships outside of his marriage.
Stiviano's court filing ridicules the notion that the "feminine wiles of Ms. Stiviano overpowered the iron will of Donald T. Sterling who is well known as one of the most shrewd businessmen in the world." Stiviano's papers, however, do not acknowledge that she was in a romantic relationship with Sterling.
