Mama June Shannon claims there's another side to Mike “Sugar Bear” Thompson that Here Comes Honey Boo Boo viewers never saw.
The reality star appeared on Tuesday's episode of The Wendy Williams Show and alleged that her ex was "very emotionally and physically" abusive after previewing a clip from the reunion episode of Mama June: From Not to Hot, where Sugar Bear loses his temper.
"There was a lot of stuff that was hid for many, many years," she said. "In this episode, y'all are going to be shocked."

Mama June claims Sugar Bear does not have a relationship with their daughter, Alana "Honey Boo Boo" Thompson, and alleges that he injured her other daughter, Lauryn "Pumpkin" Shannon. "Pumpkin's eye, that was his fault. The thing that we were showing on Honey Boo Boo, we never did," she said. "The car wreck, several things that happened on Honey Boo Boo that was kinda, like, covered up."
In an earlier interview with Page Six, Mama June also made physical and emotional abuse claims about Sugar Bear. “It’s time the world sees him for what he is,” she said. “Pumpkin's eye buckle was caused by him because he got mad. So many emotional and physical scars with the kids.”

She added, "I’m not going to put my kids through that ever again."
Sugar Bear denies Mama June's claims, exclusively telling ET that "abuse allegations are not true."
ET spoke exclusively with Mama June just five days after she revealed her shocking weight loss transformation on her WE tv show, and she was adamant that she was over Sugar Bear. "When you get rid of trash, then you become a better person," she said. "He really made me feel like s**t [and] I wanted to show him, 'Hey, I can do [whatever] I want to do'… I wanted to show him, like, I am actually worth it."
Alana also spoke exclusively with ET about her "non-existent" relationship with Sugar Bear, claiming that he makes fun of her about her size. "He calls me every once in a blue moon, so if there's a blue moon outside, he's going to call me," she said of her dad. "The other day we were on the phone ...and we were talking about something, and he was like, 'I need to cut my grass, so I was like, 'Yeah, I'll come do it. I'm [going to] need a ride mower,' and he said, 'You're gonna need a push mower, 'cause it wouldn't hurt.'"
"I was more mad of the point that he said, because I didn't get this shape from not eating," Alana added. "The other day, I was talking to him again and he said it again."
