Liberty Ross, the model/actress who is estranged from her husband, film director Rupert Sanders for his brief affair with actress Kristen Stewart, has spoken out about her feelings for the first time.

Ross attended a Chanel dinner at Madeo on Feb. 23 and was overheard expressing her heartbreak over the split from her husband.

"You have no idea what I've been through," an eyewitness told Hollywood Life she said. "It's been horrible." 

Ross' despair, however did not last very long. Another onlooker revealed that later that night, Ross attended famed photographer Mario Testino's preview at Prism Gallery. She arrived solo but was "quickly surrounded by men once inside."

"She hung on the upstairs outdoor patio and got chatted up by three handsome male models," the source told Hollywood Life.

Ross is living the single life after her husband was photographed in a passionate moment with Stewart last summer. Sanders directed both Stewart and his wife for their roles in Snow White and the Huntsman.

Ross, who married Sanders in 2002, filed divorce papers to end their marriage on Jan. 25. The former couple have a daughter Skyla, 7, and son Tennyson, 5. In the divorce petition, the actress requested joint custody of their two children, spousal support and that her attorney fees are paid by him. Sanders is also seeking joint custody, but did not request spousal support.

Ross attended the Vanity Fair post-Oscars bash at Sunset Tower in West Hollywood on Sunday, Feb. 24. She wore a sexy black sheer dress that showed her nipples and major side boob because she went bra-less.

That same night, Stewart attended the 85th annual Academy Awards with the most-talked about accessory of the night - a pair of crutches. The Twilight actress who went to present an award, reportedly told Anne Hathaway backstage during the awards ceremony that she had cut her foot recently after stepping on glass.
