Jon Gosselin's new 22-year-old girlfriend Hailey Glassman stayed in Monday night while visiting St. Tropez, France, with the 32-year-old father of eight because she was so upset with the bad press she's been receiving.

"U.S. press is all over stories about her being some slutty party girl with a history of arrests," a source tells of Glassman, who was arrested in 2005 for marijuana possession (see her mug shot). "She was upset tonight."

She didn't seem too upset earlier in the day, as she and Jon shopped at a Gucci boutique and grabbed lunch together. They were also spotted lighting each other's cigarettes while sightseeing.

The two are expected to return home today. Despite previous reports, Jon and Hailey are not collaborating with Ed Hardy fashion designer Christian Audigier on a children's clothing line.

"Christian is absolutely not starting a kids' clothing line with Jon," a rep for Audigier told Us Monday. "As of right now, there is no clothing line in the works between them at all."
