Asked in an interview with Health magazine, whose celebrity body she thinks is gorgeous, the 44-year-old singer-actress said: 'Naomi Campbell's. It's beautiful.
'I've always said if I could have one person's legs, they would be Naomi's. They're beautiful and long.'
Campbell appeared in the 1992 Herb Ritts-directed music video for In The Closet with Jackson's late brother, Michael.
And it was for another Ritts music video two years earlier that Jackson says she crash-dieted for.
Asked which diets she regrets following, she tells the US magazine: 'It was during the Rhythm Nation tour, and I had shot all the videos except for one, Love Will Never Do (Without You).
'I actually wanted to wear a dress, because I was so covered up from head to toe. And then Herb said, 'Why don't you wear jeans and show your midriff?'
'And I said, 'OK, I'm down for that'. And I decided to have an apple and one small bag of tortilla chips a day. That's all I ate…”
The For Colored Girls star added: “And I lost a lot of weight. But I gained it back and more after that.'
