Frankel admitted to Cohen that she didn't know her co-star's fiance personally, but alleged, "Ramona [Singer] dated him, and Sonja [Morgan] used to be his 'friends with benefits,' so they kind of gave a little intel recently."
While Frankel joked about D'Agostino, she share her excitement for her RHONY co-star. "I feel excited for [Lesseps]. She's having a moment. It's exciting," she said. "She wasn't that happy this summer, and I feel like who knows, I suck at relationships. I'm not one to talk about anyone's relationship. I'm in the 12-year divorce."
Lesseps' rep revealed to ET some of the romantic details of her engagement. "Thomas wanted to do the honor on Valentine's Day, but just couldn't wait and gave Luann an 8 carat canary yellow diamond ring," the 50-year-old reality star's rep said. "Luann is 'over the moon' in love with Thomas, considers him her soulmate and is so happy and grateful to have found love a second time."
