The 37-year-old supermodel - who has nine-year-old daughter Lila Grace - explained the youngster tells her off for not removing her make-up, as she prefers to see a "fresh-faced, natural mummy".
She said: "I always take my make-up off, because otherwise my daughter will come in and say, 'Mummy, tut-tut'. She doesn't like it. She likes the fresh-faced, natural mummy, when I've got my hair in a bun and no make-up on.
"Lila is quite prudish - she'll only wear a little bit of lip gloss or something. But she is into nail art. I think Lila is beautiful - she's so innocent and has that fresh face. She's gorgeous, but obviously she is my daughter."
Kate - who married The Kills rocker Jamie Hince in July - admitted her husband is always shocked when he sees her in the morning, but she is lucky as she can "scrub up" with the use of make-up.
She added in an interview with Style magazine: "Feeling happy with yourself is the key when you're getting older and still in the business.
"I can still scrub up. And that's why girls are lucky. My husband, he wakes up and is like, 'Oh God'. But girls can transform themselves with make-up."
And although it's reassuring to know one of the most beautiful women in the world feels like we do first thing in the morning, we're sure Kate doesn't have to try too hard to make herself look presentable!
