“It was the weekend before the [‘RHONY’] reunion, basically,” she told host Andy Cohen on an episode of “Watch What Happens Live.” “Tom went out, and he called up an old girlfriend, and they met up with a group of people—and I didn’t know about it. I found out about it the next day in the press. So that, for me, was like the final straw. I was like, ‘I can’t do this anymore.'”

D’Agostino appears to have disputed that narrative, saying, “I fell in love, got married quickly and am very sad that two people in love are not together. The publicized reasons for the divorce make for a great Reality TV story line. I wish Luann much happiness and love.”
