Kate Hudson has shared a naked picture on Instagram. The 37-year-old actress has followed in the footsteps of Kim Kardashian West and Chrissy Teigen by baring all in a risque photo with no clothes on as a Throwback Thursday - just because she's "pretty happy" that it's almost the weekend. Alongside the picture, in which she can be seen posing with her back to the camera in dull lighting with one hand on her hip and the other in the air, she wrote: "#tbt #PrettyHappy #LOVE #AlmostFriday cred @darren_ankenman (sic)" The blonde beauty is proud of her body and has previously written a book about called 'Pretty Happy: Healthy Ways to Love Your Body'. Talking about how important it is to be comfortable in your own skin, she previously said: "It's never too late to start that process of enjoying what it feels like to feel strong." The 'Almost Famous' star - who is the daughter of Hollywood veteran Goldie Hawn and Bill Hudson - says she was taught how to embrace her body by her mother. She said: "My mom always celebrated the female body so she gave me confidence. I felt that when I started becoming a woman and getting my figure, it was celebrated." And she's previously admitted she prefers being naked because her family have always been comfortable with baring all. She said: "My family's always been a comfortably naked family, I'd much prefer being naked than clothed, I just find clothes restricting. When I get home I just want to be naked. "When you're a dancer, you're very comfortable with your body...and my mom was a dancer,"
