Kate Hudson was talking to PEOPLE on December 12 at herHappy x Nature Eco-Evening Collection event in Venice, California. Hudson was proudly talking about her beautiful 14-month-old daughter Rani Rose.  Apparently little Rani Rose has quite the personality! “Her sense of humor is starting to come through and it’s just amazing,” said Hudson, 40. “She’s a little sneaky, which I like. She’s got some strong personality characteristics coming out, which is real fun.” Hudson is pretty sure that her daughter is getting her silly personality from her two older brothers Bingham “Bing” Hawn, 8, and Ryder Russell, 16 next month: “She’s just seeing them like, ‘These are my go-to’s’ and they’re so big, and she’s sprinting.”

Hudson admitted that her older sons have made her daughter want to grow up fast because she wants to keep up with them. The actress shared that Rani started walking and then immediately wanted to run to be able to catch up wither Bing and Ryder. “She went from walking to wanting to run,” Hudson added. “I have to hold her from falling forward, just in case, because she wants to move so fast. We’ll keep her on a little rope just to keep her from moving too fast.”

She shares how her body is just getting back to where it was post-pregnancy. She admits that she shared that it took her about 12 months to get her body where she wanted it to be. With her last child, she said it took almost half that time. “But I did it differently. I partnered with WW and I got really into the science behind what they were doing, because I had never really heard about it or known about it,” Hudson said.

Kate Hudson and her three children are planning on going to Colorado for the holidays, which is something that they do every single year. She also talked about her new fashion line. Happy X Nature’s newest evening wear collection — which features coats, dresses, tops, blazers and more in holiday-friendly hues — “is made of fabrics that contain recycled bottle yarns to help reduce the amount of waste on the planet." Hudson told PEOPLE “For us, it was, ‘We’re going to bring nature and we’re gonna take it backstage,” Hudson told PEOPLE “So, you got the metallics and then you have … I actually think this was sort of Clueless-inspired, but in a cool way. .. That was kind of after [production] when we started seeing [specific finish pieces].”
