Mariah Carey has never felt like a superstar because her marriage to music mogul Tommy Mottola prevented her from feeling "empowered" as an artist.

The Heatbreaker star has often spoken out about her five-year marriage to the former chairman of Sony Music, claiming married life with Mottola was restrictive - comparing the 58-year-old to "a strict father".

And the singer, who divorced Mottola in 1998, has penned a track about the turbulent relationship for her new album E=mc².

She tells U.s. magazine Parade, "I see other people who have one hit and they're already thinking they're the biggest star in the world. But I didn't feel that because of the relationship that I was in and because I think there was a concerted effort to keep me from feeling too empowered.

"On my new album, the song Side Effects says, 'Kept my tears inside, 'cause I knew if I started I'd keep crying for the rest of my life.' It's really true. At that point in my life (during my marriage) I didn't cry because I had to be so emotionally cut off to deal with it."

But the 38-year-old beauty blames herself for the years of torment, stating her dysfunctional upbringing made her feel as if she didn't deserve happiness - prompting her to try and make her marriage work.
