This week it was all about Paris Fashion Week and adorable puppies, with some on-set snaps and sweet baby pictures thrown in. Stars like Ciara, Lena Dunham, and Rashida Jones were all on hand for the fashion festivities in France, and also in the City of Light was Miranda Kerr , who did double duty on the runway and on the set of a photo shoot. Kaley Cuoco got a visit from her new fiancé, Ryan Sweeting, while shooting The Wedding Ringer in LA, and Bryan Greenberg urged his followers to "get covered" by the newly established Affordable Care Act. Meanwhile, it was all about snuggling with cute pups for Behati Prinsloo and Julianne Hough, and Gisele Bündchen  kicked off her morning with yoga and meditation alongside her baby girl, Vivian Brady. Rachel Zoe  and Rodger Berman, however, left their little one at home to celebrate Rodger's 45th birthday with a night on the town.
