Less than a month after separating from his wife, an insider close to Jon & Kate Plus 8 star Jon Gosselin says Jon has proposed to his new girlfriend, 22-year-old Hailey Glassman! “Jon has been telling everyone that he loves her and she loves him, so why waste time?” says the insider, adding that Jon presented Hailey with a $180,000 engagement ring designed by Edouard Nahum — featuring a skull surrounded by four black diamonds — during a romantic getaway to St. Tropez on July 12. “They started dating two months ago and they both just knew the other was the one instantly.” The couple was in the French Riviera to meet with Ed Hardy clothing designer Christian Audigier, who tells In Touch, “We had a great time.” The two stayed in a $2,000-a-night room at the Chateau de la Messardiere, drank champagne and ate lobster after an afternoon on Christian’s yacht, and went shopping in Antibes. Christian helped them celebrate their engagement on July 13. “They all went out to the V.I.P Room nightclub in St. Tropez after dinner,” says another source close to the group. “Hailey was flashing her ring around and they were kissing and hugging.”
