Just how many people did Sugar Bear cheat with?!

That's the big question looming over Mama June on Friday's new episode of "Marriage Boot Camp: Reality Stars," as she really grills him on his infidelity.

In a sneak peek clip, we see June Thompson voicing her frustrations with housemates Sean Lowe and Catherine Giudici about her man, who she doesn't believe is being honest with her.

"I believe there’s more than one," she exclaims. "The text messages that I have is [with] men and women. I want him to be fully honest. I don’t feel in my gut that he’s fully honest."

In a joint confessional, she continues, "Sugar Bear, I feel like, in my heart, that there’s maybe more you’re not being honest."

This makes him clearly aggravated, shouting back, "You keep bringing it up, 'There’s more, there’s more.' I know what I’ve done, there is no more!"

We also see the two arguing inside their bedroom, though the audio is a little hard to comprehend.

"It’s not about the shame. I need closure," June tells Sugar. "It’s about us being able to move past what we’ve done."

It then sounds like she says, "You’ve been texting men," before trailing off.

We're VERY interested in seeing where this conversation goes!

Both June and Mike Thompson opened up about their messy relationship in a very candid conversation with toofab last year.

"People are gonna see a side of Sugar Bear they didn’t see on 'Here Comes Honey Boo Boo,'" she told us at the time. "I think the fans are gonna be shocked a little bit, people in the house were even shocked because they were fans of the show. I just told him to go in there and be open and honest, it’s not a vacation."

"My biggest issues was my cheating," added Sugar. "I’ve done that and shouldn’t have and I look back on it, I regret it and I wanted to go to ‘Marriage Boot Camp’ and get the help that I need."

While initial reports on their split last year say June caught Mike trolling dating websites, Sugar told us it was "a lot more than internet chatting."

"It was really hurtful because one of it was a good friend of ours that we’ve known for quite some time," continues June, explaining how Honey Boo Boo's father had an affair with a co-worker's wife right under her nose. "The woman had been to dinner several times."
