Coming from a guy, I don't understand why women go to bed with makeup on. If it were me I would want it off before bed so I don't get the pillow full of makeup, but my guess is there's makeup that doesn't come off easily. Well, the queen of country music, Dolly Parton told the New York Times she doesn't take her makeup off when she goes to bed. She revealed that she does this every night in case she needs to be up in a hurry.
Dolly also told the New York Times, "I clean my face in the mornings. You never know if you're going to wreck the bus. You never know if you're going to be somewhere in a hotel and there's going to be a fire. So I leave my makeup on at night and clean my face in the morning."
Also during the interview, Dolly admitted that she doesn't ride the rides at Dollywood. She says, "with all my hair I got so much to lose, like my wig or my shoes. I don't like to get messed up. I'm gonna have some handsome man mess it up, I don't want some ride doing it."
So there you go, if you want to be like Dolly just go to bed with makeup on and wash your face in the morning.
