As the host teased the clip, Sammi looked like she was going to cry and quickly stormed off stage, much to the shock of her castmates. 

Ronnie chased after her. "Sammi, stop" he pleaded.

"I'm just very embarrassed right now," she was overheard saying as the show cut to commercial break.

When the show returned, Sammi appeared back on stage and explained, "I just think it was an emotional breakdown. I'm good."

But things got more awkward when the clip aired.

It showed Sammi in bed with The Situation. At one point, she admitted to Mike that she gave her number to another guy (while dating Ronnie) and also gave The Situation a kiss on the cheek.

Naturally, Ronnie was livid.

"I didn't know about that," Ronnie said after seeing the clip. "I cut girls quicker than barbers do. She can be right on the list. I really don't care."

He also called her a "liar."

"I never did anything to you; no secret footage, no secret clips online," he seethed. Sammi – known for making up and breaking up with Ronnie – then announced on the show: "We're done."

The two appeared to be back on when they popped by Us Weekly's NYC office Wednesday.

But early Friday morning, posted photos of Ronnie partying and smooching girls "this week" at the Dublin Down Tavern in Long Island, New York.
