Kate Hudson looks radiant on the cover of the new InStyle May issue for a reason—she found true love, has a baby on the way, and her new movie Something Borrowed opens May 6th. "You know how you tell a friend she looks amazing and you ask her what she's doing differently—and it turns out nothing except she met a new guy?” the actress says in this months’ issue. “Well, the best beauty advice my mom gave me was that you have to find happiness.” And she has, with boyfriend Matthew Bellamy of the music group Muse. As for whether they’ll be walking down the aisle soon, “I wouldn’t count it out,” Hudson says, adding “but Matthew and I kind of skipped that part and went right to the good stuff!” Now pregnant with her second child (as for gender: “I’m going to wait to find out”), she’s getting used to pregnancy life again, curves and all. “I'm usually an A cup and I'm getting close to a D cup,” she tells us. “Big breasts are fun for certain things and really not fun for other things. Plus, I love fashion, and having big breasts is not ideal for certain looks. They're way more fun when you're not in your clothes. Then, they're a blast!” For more of our exclusive interview with Hudson, pick up the May issue of InStyle, on newsstands Friday.
