Teresa Giudice is finally putting it all out there.

She isn't remaining silent and she isn't pretending as if her marriage only just fell apart.

On Wednesday night's brand new episode of The Real Housewives of New Jersey, Teresa accused estranged husband Joe of cheating on her.

We can't say for certain whether or not this happened, but rumors of Joe's infidelity have certainly been floating around on the Internet for several months.

This marked the first time Teresa ever said the allegation out loud in a public setting, however.

Speaking to nearly all her co-stars in a setting that definitely was not orchestrated and/or scripted, Teresa said she found a second cell phone that belonged to Joe and that she think he slept with his ex-girlfriend's sister about 16 years ago.

"I have a lot of resentment," Teresa told the group, battling tears and later adding in a confessional:

"It took a long time, and it still is really hard for me to admit, but I owe it to myself to open my eyes to it."

Teresa also said she believes Joe cheated on her far more recently, but failed to elaborate on why she thinks this or when the newer infidelity may have taken place.

(Joe and Teresa separated in December after two decades of marriage and four daughters together.)

This brings us back to Wednesday night and Teresa appearing on The Real Housewives of New Jersey after-show alongside a producer and co-star/childhood friend Dolores Catania.

Teresa once again mentioned the second cell phone and how she asked Joe about it and "he just said it was to talk to this one person because they grew up together."

Catania was left seething over the whole thing, turning to Teresa and claiming this other woman "went out with Frank, too, okay?"

"Yeah, she gets around," Teresa responded, as both women shook their heads in disgust. 

To make matters worse, and sort of harder to believe, Teresa added that the mistress was also "training me at the time."

"I never had proof. I asked!" she continued.

"I confronted her. I confronted the girl, and she denied it, of course. So I never got proof, so that's why I got over it. But now, because of everything that happened, I play it in my head. Like, this, this, this, this."

How did this woman justify her contact with Teresa's then-husband?

Giudice didn't say on the program.

However, the excuse Teresa claimed she got from Joe was that he was simply "helping" the lady after her divorce by "trying to sell her house."

Teresa believed it outwardly and locked away whatever hurt or sadness she felt to keep the peace and her family intact.

She went on to have three more kids with Joe.

"Listen, I don't think it's news to anybody's ears that Joe was cheating on Teresa," Melissa Gorga said in a show confessional this week, reiterating what we said above:

"The news here is that Teresa's finally admitting it."

Joe, of course, is now living in Italy as he awaits the ruling on his final deportation appeal.

He continues to drool over Teresa from afar, but has also leveled a serious allegation against this reality TV star himself.

As summarized below in case you forgot, Joe also thinks Teresa cheated on him:
