After co-founding her activewear line, Fabletics, Kate Hudson was inspired to share her experience and insights on leading a healthy and active lifestyle with others in her new book. Last night, Fabletics hosted a private event to celebrate the release of co-founder Kate Hudson’s new book, Pretty Happy: Healthy Ways to Love Your Body. The shindig took place at cool hot spot Gracias Madre in West Hollywood, and brought together Kate’s closest friends including Molly Sims and Rachel Zoe to toast the launch. Goldie Hawn was all smile on the red carpet as she celebrated her daughters company and new book. Guests walked the red carpet prior to heading inside for a night of fun that included a Fabletics pop-up shop and a photo booth.
