Mariah Carey, 41, unexpectedly dropped out of Tyler Perry’s new film on Tuesday, adding to recent speculation that she may be pregnant, according to People. The star, who has been married for two years to singer-actor Nick Cannon, 29, was set to start shooting next month for a big-screen adaptation of the 1975 play For Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf. A rep for Carey declined to confirm or deny pregnancy rumors, telling People, “I’m not at liberty to discuss her personal life at this time.”
