The singer made the comments in the forthcoming two-part documentary Janet, which is set to premiere in the US on Friday (January 28) before it airs in the UK next week (January 31).
“I’m an emotional eater, so when I get stressed or something is really bothering me, it comforts me,” she recalled. “I did Good Times, and that’s the beginning of having weight issues and the way I looked at myself.
“I was developing at a very young age and I started getting a chest, and they would bind it so I would look more flat-chested.”
Janet then recalled how Michael would “call me names” in regards to her weight.
“There were times when Mike used to tease me and call me names. ‘Pig’, ‘horse’, ‘slaughter hog’, ‘cow’,” she said.
“He would laugh about it and I’d laugh too, but then there was somewhere down inside that it would hurt. When you have somebody say you’re too heavy, it affects you.”
A synopsis for Janet reads: “Janet has enjoyed immense success but also seen incredible tragedy. She has endured a tumultuous private life in the face of extraordinary public scrutiny.
“With no stone left unturned, Janet Jackson lifts the lid on her private life for the very first time and reveals the most intimate moments of the star ever caught on camera.”
