Mariah Carey doesn’t celebrate her birthday

She said: “I don’t have birthdays. Literally. If anyone wished me happy birthday, I’d be like, ‘Who are you talking to?’ It’s about not being tied down to anything.”

The ‘Hero’ hitmaker insists she lives outside of the usual restraints of society and has no interest in being on time for anything because she doesn’t want to be restricted.

She explained to the Independent newspaper: “Honestly I don’t think I’m normal. I don’t think my life has been quite normal. I disregard time, you don’t see me wear a watch. I don’t adhere to modern rules or the normal rules of time.”

However despite her quirks and diva reputation, Mariah thinks she is a dream employer because she cares about her staff.

She said: “I can be difficult but I’m pretty nice compared to most people I’ve seen do what I do. If you want to work for someone difficult, work for a bank or company where people don’t care about you. I take care of a lot of people and it’s not easy.”
