Stars had lots to celebrate this week and made sure to share their cute snaps through social media. There was a star-studded turnout for Stella McCartney's Spring collection party, and the designer snapped photos with friends like Cameron Diaz and Kate Bosworth — not to mention her dad, Sir Paul. Nicole Richie also spent time with her famous father, Lionel, and posted a sweet pic to her feed. Models like Gisele Bündchen and Miranda Kerr shared fun selfies while hanging out at home, while Lily Aldridge and Erin Heatherton were on hand to watch Kings of Leon perform at the Governors Ball festival. Chrissy Teigen and Irina Shayk struck sexy poses, and two of our favorite funny guys, Seth Rogen and Andy Samberg, flanked Kelly Ripa for a sweet snap on set.
