Last week, In Touch reported Jon Gosselin’s engagement to party girl Hailey Glassman, his girlfriend of two months. And now, the jeweler to the father of eight has confirmed the TLC reality star’s intent to wed the 22-year-old. “Yes, we sold Jon Gosselin the engagement ring that he gave to his fiancée,” Edouard Nahum tells In Touch. “It was a great pleasure for us to sell this ring. Our brand is very well known by people and stars in Europe.” Jon, who announced his separation from wife Kate last month, presented his new love with a ring dripping in black diamonds while vacationing in St. Tropez on July 12.
