Just weeks after splitting from his wife of 10 years, Jon Gosselin is back in the spotlight with a new career and a new girlfriend. Gosselin, 32, turned up in St. Tropez hand-in-hand with Hailey Glassman, the daughter of the plastic surgeon who performed Kate's tummy tuck in 2006. The lovebirds spent the weekend along the French Riviera so Gosselin could finalize a deal to design his own line of children's clothing with Ed Hardy designer Christian Audigier. Glassman will also have a hand in creating the kid-friendly fashions. "She'll have a lot of input with Christian," Gosselin told PEOPLE of Hailey's involvement. "And I will, too."
