You never forget your first love.
At least that's the case for Liberty Ross, who was spotted cozying up to a mystery man earlier this week, who has just been revealed to be her former lover, museum director Christopher Taylor. On Sept. 17, the pair sparked rumors of a romance when they were spotted holding hands as they left the Serpentine Gallery party in London.
Ross, whose husband, director Rupert Sanders, was caught cheating with his "Snow White and the Huntsman" star Kristen Stewart in July, was all smiles at the event and seemed to be smitten with her former flame as they stayed close by each other all night.
The model and Taylor, both 33, first went public with their relationship in 2001 after they were seen canoodling at a fashion party. Following their breakup, Ross met and married Sanders, with whom she has two young children, Skyla and Tennyson.
And although Sanders, 41, is trying everything to put the pieces back together after his now-infamous cheating scandal, it appears his wife is moving on with a new man. Not only did she pack up and ship out of their shared Los Angeles home and move back to London, but Ross has ditched her wedding ring for single nights out on the town with her ex-boyfriend.
