Mariah Carey’s voice, famous for having a range of five octaves, is stronger than ever, according to the Associated Press. Now 70 lbs. lighter, thanks to Jenny Craig, the singer attributes the change in her voice to her pregnancy.

“Right now I feel like pregnancy actually helped me vocally,” she says. “At this moment my voice is in great shape.”
