It was all about mixing work and play for celebs this week, and even while on the job, they still made time to share their fun moments via social media. Jessica Alba  and Zach Braff  both got visits from little ones on the set, while Jonah Hill  got strapped in before doing some stunts for 22 Jump Street. Katie Holmes  bundled up from the cold while shooting The Giver in South Africa, and on the set of Modern Family, cast members Eric Stonestreet and Sofia Vergara were joined by special guests Jane Krakowski and . . . baseball player Brian Wilson? Everything was rosy for Gisele Bündchen  on a Colcci photo shoot in NYC and Mindy Kaling cozied up to her costar Adam Pally — and whether or not Chord Overstreet was actually peeing, we just hope that's a fake police car that he's standing on.
