"Here Comes Honey Boo Boo" star Mama June Shannon is making some serious cheating accusations about her hubby Mike "Sugar Bear" Thompson.

In a new clip for the upcoming episode of "Marriage Boot Camp: Reality Stars," Shannon tells "The Bachelor" couple Sean and Catherine Lowe that she believes Thompson might have cheated on her "with men and women."

The bombshell was dropped after Shannon walked out of one of the show's counseling session and begins ranting about Thompson not being honest with her regarding his alleged affairs and cheating behaviors, according to a clip obtained by Entertainment Tonight.

"It's not that I don't want to talk to him," she told Lowes. "It's just that, you gotta kind of process, because I know that it was there. But I believe there's more than one. The text messages that I have say men and women."

"I just feel like, in there, that was supposed to be this monumental, game-changing moment. And it wasn't. Because you still don't trust him," Sean Lowe told the reality star. Shannon replied, "I want him to be fully honest and I don't feel it in my gut that he's fully honest..."

Shannon admitted that she wanted closure about Thompson's past so that they could move forward with their relationship. Despite her ranting, Thompson continued to stand his ground, claiming, "You keep bringing it up. 'There's more, there's more. I know what I done. There is no more."

The two separated in 2014 after rumors persisted that Thompson was cheating on Shannon using the online dating site, PlentyOfFish.com, an online service described as a "great platform that allows our users to come together to communicate and share with each other," as previously reported by HNGN. 

"Sugar Bear and I have decided to take some time apart to figure out some things in our relationship," Mama June said in a statement at the time, according to TMZ. "We want to thank y'all for your support."

The couple are on the reality show attempting to mend their relationship after a tumultuous couple of years. In May 2013, the couple held a commitment ceremony and exchanged vows in front of their children in their Georgia backyard. However, the two are not legally married.

TLC cancelled the family's show "Here Comes Honey Boo Boo" after reports suffered that Shannon was dating convicted sex offender Mark McDaniel, who allegedly molested her daughter Anna "Chickadee" Shannon in 2002.

"Marriage Boot Camp: Reality Stars" airs Fridays at 9 p.m. on WEtv.
