Welcome to Instagram, Anne! Our September cover girl’s first post ever: A video of her talking directly to the camera before soaking herself for the ALS Ice Bucket Challenge. Like many of her 800,000+ followers, we smiled, double-tapped, and have since followed her every post about pushing for equal rights, her love of animals, and the occasional unguarded selfie.

Seems you can teach a Golden girl new tricks. The talented Ms. White is an old pro at Twitter (where her 1.2 million followers turn for updates on her projects), but it wasn’t until June that she dove headfirst into Instagram, sending her 215,000+ followers shots of her hanging out with friends (both human and canine), snapping selfies, and generally adding a much-needed smile to our days.

Marc Jacobs’s Instagram (which has only been going since spring) looks a lot like your best friend’s, filling his 260,000+ followers’ feeds with shots of him laying in bed, eating food, hitting the gym, and going to parties. Of course, his also features an absolutely fabulous parade of A-listers (from Miley to Cher to Miss Piggy), photo shoot set shots, and one insanely adorable dog.

The soon-to-be Ghostbuster joined Twitter and Instagram this year, and if her stream of smiles and red carpet selfies with folks like Spy costar Jason Statham are any indication, this girl is having the time of her life. And is it just us, or did no one walking by her in that Eiffel Tower shot have any idea that they were in the presence of a comedy queen?

The biggest surprise from the Deadpool star’s social? Just how darn funny he is IRL. While his Instagram is filled with fun shots of fans and animals alike, his Twitter is a Seinfeld-grade stream of one-liners that ask the tough questions of his 575,000+ followers, such as whether the ocean is, in fact, full of sharks huddled underwater watching Human Week.
