Marriage Boot Camp: Reality Stars couple Mike "Sugar Bear" Thompson and June "Mama June" Shannon deal with a huge confession on Thompson's part when the next episode airs January 15.

As shown in an explicit Marriage Boot Camp preview clip obtained by People, Thompson, 64, admits he's hooked up with men -- confirming a longtime suspicion of Shannon's.

During a private conversation between the former Here Comes Honey Boo Boo stars in their bedroom, Thompson asked if he could tell Shannon something, and she was all ears.

"Don't bring this up with nobody else 'cause I don't want this out there: I have experimented with guys," Thompson revealed.

Reports surfaced last week that Shannon had feared for a long time Thompson was cheating on her with both women AND men.

While Thompson admitted intimacy with men is "not my cup of tea," he later insisted, "It's just something I was curious about, experimented with it, and it's over with and done with, and that's it. [It] won't ever happen again."

Regardless, Shannon, 36, was furious and yelled out "bullsh-t!"

Thompson then elaborated on what he meant by having "experimented" with guys.

"I got my d-ck sucked," he noted.

Shannon said Thompson's confession "validated" her fears because she had previously discovered sexual photos on his phone of other men. Thompson, however, denied the allegation.

"Again... another lie!" Shannon screamed. "We was trying to work on our relationship."

"But I don't want everybody to know that lie," Thompson explained.

Marriage Boot Camp: Reality Stars airs Fridays nights at 9PM ET/PT on WEtv.
