Los Angeles - Mariah Carey refuses to go into a supermarket.
The Hero singer is renowned for her diva reputation and she admits she never does her own food shopping because of the "bad lighting" in grocery stores.
She explained: "It's pretty bad lighting in the grocery store. Have you noticed it's fluorescent lighting?"
Meanwhile, the 46-year-old singer admitted does her best to make things as close to "perfect" as she can for her children, five-year-old Moroccan and Monroe - who she has with estranged husband Nick Cannon - but admits the kids "frustrate" her at times.
She told Entertainment Tonight: "They have strong personalities and they are pretty amazing. They make me laugh.
"They frustrate me sometimes. But they are great... I can't make things perfect them but I try my hardest to always make them happy."
