THIS IS NOT A DRILL. YOONA HAS JOINED INSTAGRAM

YoonA has finally joined the rest of the members and signed up to the photo sharing website. YoonA joined the website last week, has followed all of her members and made several posts already.

Not surprisingly, YoonA has quickly gathered a lot of followers, currently 1.1 million users are following her. She has a way to go before she reaches the same followers as Taeyeon (5 million) and Tiffany (2.7 million) but we reckon she'll catch up with the other girls soon enough.

If you'd like to follow YoonA on Instagram, her username is Yoona__Lim.
