Looks like the estranged wife of Kristen Stewart's "Snow White and the Huntsman" director, Rupert Sanders, is moving on from the cheating scandal that rocked her world earlier this summer.

Liberty Ross was photographed holding hands and cozying up to a mystery man in London following the Future Contemporaries party on Monday night at the Serpentine Gallery. Sporting a fur coat, leather pants and a T-shirt, Ross was all smiles as she left the party arm-in-arm with the dapper gentleman, who was dressed to the nines in a navy suit.

Noticeably absent from Ross' ensemble was her wedding ring, which she hasn't been wearing since photos of her husband and Stewart's July 17 affair surfaced in Us Weekly.

So, will Ross forgive her husband of 10 years, who is the father of her two children, 7-year-old Skyla and 5-year-old Tennyson? "It's still too early to tell what will happen with them," a source close to the couple tells Us Weekly.
