Looks like Kate Hudson has put her hard-partying days behind her.

The 33-year-old actress and mother of two tells Elle's UK edition, "I'm a lot less a rock chick and a lot more about being a good mother, a good partner.

"I'm part of a family," the "Something Borrowed" star told the magazine, which hits newsstands today. "That's how we were brought up, how I bring my kids up. They are very blessed to live how they do but they are aware of that."

Hudson opened up to the magazine about her relationship with rocker Matthew Bellamy, with whom she has son Bingham, nearly two.

"It was all very old-fashioned and proper and we went on lovely dates," the actress said of meeting Bellamy, the frontman of the British band Muse, at the Coachella music festival in 2010. "And two months later I was pregnant."

"[I was shocked], but I also thought: 'This is going to be interesting,'" she said.

"I knew it would take a strong man to deal with it. You know that with a relationship, things can go either way when you have a child," said Hudson, who is also mother to nine-year-old Ryder from her previous marriage to Black Crowes rocker Chris Robinson.

"When you get pregnant everything changes; you, your body. Everything becomes a big decision. But he was there and that was that. Now it's three wonderful years later. Things happen for a reason."

As for when she and Bellamy will tie the knot, Hudson said, "We will get married. I do think it's important but we have no plans. [Ryder] wants a party. For me it's not the legal part that is important, it's what it means to the family."

That's because Hudson is the daughter of actress Goldie Hawn and her ex-husband Bill Hudson, but was raised by her mother and Hawn's partner of 30 years, actor Kurt Russell.

"When I was a kid, my brothers and sisters and I wanted my parents to get married. We ended up with something far more powerful," Hudson told Elle, according to People magazine. "We were all together at home, Dad gave Mum a ring and said some beautiful words. It was their own version of the ceremony and I remember it so well. It was like it was about us. The family was the glue."
