REAL HOUSEWIVES' AWFUL EXES!

INSENSITIVE much?

Neither Luann de Lesseps nor Vicki Gunvalson is particularly known for their tact —but even these Real Housewives vets deserved better from their exes. For starters, on Dec. 31 — five years to the day of their wedding — Tom D’Agostino popped the question to girlfriend Danielle Rollins, showing off her massive sapphire ring on Instagram. Ouch! But Luann, 56, who split from her playboy ex after just seven months, tried to shrug off the bad timing. “I’m not somebody who dwells in the past,” she told Page Six. “I’ve moved on and I only wish Tom the best.”
