Mariah Carey is pregnant, according to RadarOnline.com. The pop diva, 40, who’s getting plumper by the hour, dropped out of Tyler Perry‘s latest movie because of her condition. Carey has recently gone to great lengths to hide her baby bump from photographers, the Web site reported.

Reps for Carey and hip-hop hubby Nick Cannon didn’t respond to requests for comment. At the Film Independent Spirit Awards in March, Carey — who could barely walk in her sky-high heels — told Page Six she had “something special” on the way. The couple got hitched in 2008.
