Jon Gosselin Parties With New, Young Mistress in Saint Tropez

While his estranged wife Kate was at home taking care of their eight kids, Jon Gosselin was partying with a wild new mistress in the South of France.

Gosselin, 32, was snapped with Hailey Glassman, the 23-year-old daughter of the plastic surgeon who performed Kate’s tummy tuck, aboard designer Christian Audigier’s yacht.

Rumor has it that the “Jon and Kate Plus 8” star is working on designing a children’s clothing line for Audigier’s mega-successful Ed Hardy line.

Fans were shocked to see Jon out with a new woman, especially since his wife only filed for divorce weeks ago and the “other-woman” in the scenario was a different 23-year-old mistress – teacher Deanna Hummel.

Jon was snapped with Glassman on Memorial Day weekend, but he downplayed the relationship as being nothing more than a friendship. But the new photos, where he is spotted holding hands and embracing Glassman, suggest much more than friends.

More troubling, Glassman has quite a reputation for being a wild-child. According to a report in Us magazine, the actress was arrested in 2005 for drug possession. Radaronline also obtained photos of her partying hard with bottles of rum and putting a gun to her friend’s head.
