Instaglam: Will Smith
In fittingly A-list style, he joined Instagram while appearing as a guest on The Ellen Show. He opened with a number of duck-faced selfies, and has since become a fan of posting videos. So far, our favourite moments include the Christmas video where his wife, Jada, makes the entire family go sleighing; Will recounting life advice from Arnold Schwarzenegger — for the impressions, obvs; his camera-gear shopping haul on joining YouTube; and Jada, every time she pops up.
