The “New York Post” says that MARIAH CAREY underwent gastric sleeve surgery last month . . . because people have been teasing her about her weight online. A source says, quote, “Mariah has always been proud of her curves, but [recently] . . . she noticed it became harder to dance, and she was getting a lot more criticism online from body shamers.” On a related note, Mariah is a finalist for the 2018 class of the Songwriters Hall of Fame, along with N.W.A., John Mellencamp, Alice Cooper, Tracy Chapman, Tom Waits, Alan Jackson, and more.
