Patti Stanger just dropped some massive gossip.

The Millionaire Matchmaker star appeared on Watch What Happens Live with Andy Cohen this week when a viewer called in to ask if she’d ever suspected anything between Mario and Ramona Singer. The reality couple confirmed their divorce last year.

Stanger shocked viewers when she admitted she witnessed Mario's infidelities with her own two eyes, saying, “Yeah, I was there that night." She claims she saw the "entire thing go down."

That wasn’t all though. The Bravo personality detailed the situation, saying, “I saw him pick the girl at a certain person’s house you probably know. It was a big dinner party and we just came for dessert.”

According to People, Stanger did reach out to her friend following the situation in the Hamptons and told the reality star she was taking her side. Since the divorce, Singer told E! she is on the New York dating scene and doing "great."

Stanger did vouch for the Real Housewives of New York City star, saying that she didn’t deserve to have her husband cheat on her, “she’s a great girl.”
