Summer is here, and our favorite style stars have wasted no time in sharing their sunny-day photos through social media. This week, we got a glimpse of Gisele Bündchen during a rain storm in Paris and a sweet snap of Chrissy Teigen posing with her pups. Eniko Mihalik and Lindsey Wixson got glammed up for the amfAR Inspiration Gala, while Solange kept it retro-cool for a day spent soaking up the sunshine. Kate Upton looked "happy" during a photo shoot, and a reportedly pregnant Rachel Zoe teamed up with the Make a Wish Foundation to design a handbag. Also, can you guess which model shared a snap while hanging in a hot spring in Iceland?
