Dolly Parton sleeps with her make-up on - in case there's an earthquake.

The '9 to 5' hitmaker - who has been married to Carl Thomas Dean for 48 years - believes on being camera-ready all times, even in the middle of the night.

She said: ''I would go wig-less, but I put little hot rollers in my hair in the morning and a little scrunchie but I would not answer the door without some make-up or hair. No.

''I spend a lot of time in California, and you know, they're always prone to have earthquakes, I never take my make-up off at night, I always keep it. Cause, I thought, if I have to run out in the streets you know, I have to look good cause you know there are going to be cameras everywhere.''

The 68-year-old country music legend admitted she would consider going bare faced if her husband was faced with a medical emergency - but would have to ''really think'' before doing so.

Speaking to talk show host Wendy Williams, she said: ''The only way I'd go out without make-up and my hair done up a little bit is if my husband had a heart attack, and I'd have to really think about it.''
