More Secrets Exposed! Sugar Bear Admits Sex With Ex-Wife In Truck Following Gay Confession

Yikes!

On the heels of his confession he "experimented" with men, Mike "Sugar Bear" Thompson has even more bombshells to drop on his on-again, off-again partner, Mama June Shannon.

In RadarOnline.com's exclusive preview clip from tonight episode of Marriage Boot Camp: Reality Stars, the 43-year-old father of Alana "Honey Boo Boo" Thompson sits down for some serious talk with Shannon and Marriage Boot Camp counselors Jim and Elizabeth Carroll.

"I feel like there may be more," Shannon, 35, says of her common-law husband's infidelities. "Whether it's going to kill me or make me better, I want you to be completely honest."

"Actually, I'm going to be honest, there is," he responds sheepishly.

He admits to cheating with an unspecified woman who "seduced" him twice.

"Was there three, four, five, ten, fifteen, whatever. I need closure!" a frustrated Shannon says.

Then he confesses to sleeping with his ex-wife in his car!

"I stopped there, but I didn't get out of the truck. One time!" he insists.

Lastly, Thompson says he attempted to sleep with a girl in Dublin— likely a town near their native McIntyre, Georgia, not Ireland— but the motel tryst fell through.

"I did not sleep with her," he swears. "When I got there she said, I was not what she was wanting."

As RadarOnline.com previously reported, Thompson and Shannon split in September 2014 amid rumors he cheated with women he had met online. Soon after, Shannon was caught canoodling with her ex, a man who spent ten years in prison for molesting her oldest daughter Anna, now 22, as a young girl.
