Sugar Bear Loses His Temper at Mama June on 'From Not to Hot' Reunion, Storms Off During Profanity-Laden Rant

Mama June also claimed on Tuesday that her ex was 'very emotionally and physically' abusive during their relationship.

Mama June Shannon and Mike "Sugar Bear" Thompson may have made their peace at his wedding on last week's Mama June: From Not to Hot, but it seems their friendliness didn't last long. 

In a new promo for Friday's reunion episode of the WE tv series, Sugar Bear explodes on his ex when they have a discussion about him spending more time with their daughter, Alana "Honey Boo Boo" Thompson.

"There's several people here who have been in our lives, our bodyguards, who he could go to and say, 'Hey, can you come bring Alana to me?' and he knows in his self that I would not say no," Mama June says in the clip. "He knows that."

"I don't believe that," Sugar Bear replies.

"Sugar Bear, please. For once, be honest with you," Mama June pleads, setting Sugar Bear off.

"I'm finna get on you right now," Sugar Bear yells to Mama June, to her daughter Lauryn "Pumpkin" Shannon's shock. "It was every f**king weekend! Every weekend, I went up to see Alana, and it was going good, and then you're talking about, 'Well, we're going to be busy this weekend. We're going to be out of town.'"

"But I tell you what, I've got a lawyer on the case! You're going to get the paperwork. That's all I got to f**king say," he continues, rising out of his seat and storming off. "F**k it, I'm done! I've had this sh*t!"

While Sugar Bear's new wife, Jennifer, watches in horror, Mama June keeps cool.

"This is what happens," she tells Jennifer as Sugar Bear continues to scream off-set.

"Shut your f**king mouth, June Shannon, that's what happens, you stupid b*tch!" he shouts, before elbowing a door in frustration.

According to Mama June, this isn't the first time Sugar Bear has gotten upset. In fact, the mother of four alleged that her ex was "very emotionally and physically" abusive during her appearance on Tuesday's Wendy Williams Show. 

"There was a lot of stuff that was hid for many, many years. In this episode, y'all are going to be shocked," she said, before alleging that several injuries seen on the families' previous show, Here Comes Honey Boo Boo, were covered up to protect Sugar Bear.

"Pumpkin's eye, that was his fault. The thing that we were showing on Honey Boo Boo, we never did," she claimed. "The car wreck, several things that happened on Honey Boo Boo that was kinda, like, covered up."

According to Sugar Bear, however, Mama June's claims are not true.

“The abuse allegations are not true," he told ET on Tuesday. "It is not true, any of it."
