The Olsen Twins are known for being totally MIA on all personal social media. (Looks like all that detective work gave them expert skills when it comes to being secretive.)

In fact, they have never gone through the modern day rite-of-passage of posting a selfie on Instagram…Until now. Mary-Kate and Ashley took over Sephora’s Instagram account for one day to give us a look into their day as Designers and Creative Directors of their clothing brand, Elizabeth and James.

And their very first post? A black and white selfie wearing chic shades (Ashley is on the left and Mary-Kate is on the right, if you couldn’t tell).

After that gem, the pair took us behind-the-scenes and gave us a sneak peek at future projects, their lunch, and how they celebrate at the end of a long day. Here’s the rest of their takeover:

Sadly the two promised that this would be their first and last takeover.

Fingers crossed that they got hooked on the ‘gram and will change their minds.
