Mariah Carey is known for her five-octave range, and she says her voice has gotten stronger, thanks to pregnancy.
The 42-year-old gave birth to fraternal twins in April via C-section. She recently lost 30 pounds by following the Jenny Craig diet, and says the process has enhanced her vocals.
Says Carey: "Right now I feel like pregnancy actually helped me vocally."
Carey is the new brand ambassador for Jenny Craig, which is now called Jenny. The Grammy-winning singer said after giving birth she was "approached by a lot of different companies," but that the folks at Jenny "understood me."
During her pregnancy Carey dealt with gestational diabetes and toxemia. She says "you couldn't make me go through that again."
