The 'How to Lose a Guy in 10 Days' star - who has three children - has always grown up with her mom Goldie and her stepfather Kurt Russell being open but insists it is always in a "classy" and not in a "crass" way.

Speaking to Conan O'Brien, she said: "They were very open when I was growing up and they still are to this day. Sometimes mom will share something with me and I am like, 'Mom, that is just [too much]'. Everything was very open. My parents are open, but they are not crass. They are classy open."

Kate had previously revealed she "talks a lot about sex" with her mother, as she revealed it was her mum who taught her how “fun” sex can be.

In a joint interview, Kate said: "What did you teach me about sex? There are so many things. We talk a lot about sex. Surprisingly."

Giving her opinion, Goldie added: "I’m not a prude. I love sex."

And Kate replied: "Oh, that’s right. And then she said, 'Sex is so much fun. But it’s better when it’s with one person.' And that was a good lesson."

The ‘Almost Famous’ star said her mother first spoke to her about sex when she was trying to explain how "sexually oriented" she was.

Explaining how the conversation came up, she added: "You were trying to engage and asking like what was going on with me sexually. I was like, ‘Mum, let’s just say that I’m kind of a sexually-oriented type of personality.' And she goes, 'Please, I have known that since you were two years old.' I was like, 'Mum!'"
