Sugar Bear may have been preaching "big is beautiful," on Mama June: From Not to Hot, but according to Alana "Honey Boo Boo" Thompson, her dad has been making mean-spirited comments about her weight.

During a sit-down interview with ET's Jennifer Peros on Tuesday, Honey Boo Boo opened up about her "non-existent" relationship with her father.

"He calls me every once in a blue moon, so if there's a blue moon outside, he's going to call me," the 11-year-old reality star revealed.

"The other day we were on the phone and we were talking about -- I don't know how we got on the subject -- but 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,'" she recalled.

"[He said] 'It wouldn't hurt if you lose weight,' and I think that was the most ignorant thing that he ever told her," Honey Boo Boo's mom, Mama June Shannon, interjected. "I would never say that."

While Honey Boo Boo agreed the comments were hurtful, she claims it's not the only time Sugar Bear has made fun of her weight.

"I was more mad of the point that he said, because I didn't get this shape from not eating," she said. "The other day, I was talking to him again and he said it again."

Mama June, who has let her 300-pound weight loss play out on camera -- and even got into a heated fight with Sugar Bear about feeding their daughter unhealthy food -- said it makes her "ill" to even talk about her ex.

"I mean, it pissed me off, I'm not gonna lie," she confessed. "But I mean, I don't wanna talk about this. It makes me ill every time I talk about him, I'm sorry."
