Mariah Carey doesn't acknowledge her age

Singer Mariah Carey, 45, says she remains oblivious to age.

"I think I have to remain eternally oblivious to age," she told people.com, adding: "Honestly, when you put a number on it yourself, it's just like, Why? Why do that?"

Carey, who has her first make-up collaboration in the works with M.A.C Cosmetics, a champagne lipstick called "All I Want", says that a "good hair and make-up team" keeps her feeling beautiful.

Carey also shared that she prefers to wear as little make-up as she can.

"If you're not wearing a lot of make-up, you don't have to take a lot of it off. So, my goal is to wear the least amount of make-up possible so I don't have to steam my face and take it all off."
