Country princess Carrie Underwood sat down recently with the folks from Glamour magazine and admitted that she’s a calorie counter and watches her diet faithfully, monitoring everything she eats and admits she’s slightly obsessive-compulsive about it all: 

“I’m slightly obsessive-compulsive about what I eat, more than I should be. I write down everything I eat. I started doing it last year. And in the last year is when I’ve gotten more healthy and lost weight.”

She also told the magazine that she’s been able to hit up some fashion shows in New York and can tell her Christian Louboutins from her Manolo Blahniks:

“….But, yeah, I’ll go home and one of my friends will say, “Oh my gosh, those shoes are so cute.” And I’ll say, “Oh, they’re Christian Louboutins.” And they’re like, “What?” So yeah, I’ve definitely learned more names.

She also admits to dropping a lot of cash on cosmetics:

“I am awful with the makeup! I have a gigantic makeup case, more makeup than any girl should have in her lifetime. Yet every time I go into a makeup store, I spend a ridiculous amount of money.”
