Blac Chyna is none-too-thrilled with haters criticizing her pregnancy weight. The soon-to-be Kardashian took to a celebrity fan Instagram account to lash out at fans, who called her "fat" and "gross." "I AM HAVING A BABY. Exactly what do you expect to see? If I walked out in makeup and heels everyday to be beautiful to your means I WOULD BE MISERABLE AND UNHAPPY," she said.
