When it comes to social snaps, double the stars means double the fun. This week, we saw PDA from Jessica Simpson  and her fiancé, Eric Johnson, and a silly moment with Chrissy Teigen and John Legend ; cute duos like Khloé Kardashian and Mason Disick, Taylor Swift  and her "hero" Ina Garten, and BFFs Anna Kendrick  and Aubrey Plaza having fun; and some sweet throwback photos featuring Lea Michele  with her late boyfriend, Cory Monteith , and their costar Dianna Agron . The biggest group of stars was the Pretty Little Liars cast, who re-created Ellen DeGeneres's epic Oscars selfie , though one other photo may top it: Gisele Bündchen  and a teeny tiny puppy.
