Hmmm, could it be that the singer is referring to Kim 'my marriage lasted for 72 days' Kardashian?
The singer made the catty call at a Jenny Craig press conference, where she debuted her post-baby weight loss and spoke about her marriage to Nick Cannon.
"Sometimes we make each other mad, that's why we aren't divorced after four months," she said, adding: "I'm not going to put on a fake face."
According to the Daily Mail the press conference crowd let off a bit of a gasp after Mariah's snarky remarks, leading her to apologise.
"I'm sorry, I'm just saying," she said.
Meanwhile, Mariah's been out and about flaunting her new post-baby bod, courtesy of the Jenny Craig diet program. The singer says she lost 30 pounds, or about 13 kilos, by eating 1,500 calories per day and working out three times a week.
