Mariah Carey 'lives in a bubble'

Mariah Carey "never has any normal interactions".

Damion Young, the star's ex-boyfriend who worked with Mariah, 45, on hits such as 'I Still Believe' and 'Irresistible', has revealed the multi-platinum selling artist lives her life in a "bubble", claiming she doesn't have normal social interactions with others because of her fame.

He explained: "Mariah lives inside a bubble. I lived inside her world for a while but I had to get out for my own sanity.

"The thing I remember most about being with her was the quiet and the loneliness. She didn't have many friends."

Damion said Mariah leads a surreal existence that he ultimately found "frightening".

The record producer told the Daily Mail newspaper: "She never even sees a bell person, never has any normal interactions. The only time she sees her fans they are screaming and pushing to get at her. It's frightening. It's life in a bubble."

Despite the failure of their relationship, Damion revealed he's still in love with the singer, who has four-year-old twins Monroe and Moroccan with her estranged husband Nick Cannon.

He admitted: "I loved her then and I love her now."
