While Amber Marchese has been the new girl under the most controversy on The Real Housewives of New Jersey, Bravo has revealed that it is Teresa Aprea who will face a huge battle in Sunday's episode.

Amber Marchese Slams 'Barbarian' Nicole Napolitano & Melissa Gorga

While Aprea and her husband Rino Aprea are going strong now, they were divorced at one point and Teresa admitted that he messed with lots of women, particularly strippers. Still, she didn't mind because they weren't together at the time. But what she might not have expected was for him to have had an affair with her own mother!

Teresa Giudice's friend Victoria Gotti dropped the bomb to Giudice and Marchese.

Gotti confessed that she and Rino had a conversation in which he reluctantly admitted his decision to cheat with his mother-in-law.

Giudice and Marchese were obviously shocked by the news.

Giudice yelled, "What?! Are you kidding me? Was he drunk?"

Marchese later told cameras, "I don't necessarily know if it's true or not. The thought that Rino slept with Santa. It would've been better if I heard Rino slept with Nicole. I get that, it's not too shocking. [They're] twins, so it's understandable."

Giudice also said she wasn't sure if it was true but added, "Things happen."

Gotti then said she told Rino he doesn't need to kid around like that because it could turn into a messy rumor. She said he then told her, "I'm not joking."

She also confirmed that that is indeed the reason they called it quits on their marriage previously.
