According to Janet Jackson, her brother Michael could be cruel when they were growing up and you adults.

“There were times when Mike used to tease me and call me names... 'Pig, horse, slaughter hog, cow.' He would laugh about it and I'd laugh too, but then there was somewhere down inside that it would hurt," she says in a new documentary 'Janet.'

According to Janet, she struggled with her weight, which made MJ's comments particularly hurtful.

“I’m an emotional eater, so when I get stressed or something is really bothering me, it comforts me," she explained. “I did Good Times and that’s the beginning of having weight issues and the way I looked at myself."

Despite the barbs, Janet said she and Michael were close when they were younger.

However, they drifted apart as adults.
