Girls' Generation's pretty girl YoonA is on Instagram!

If you have been on your Instagram game lately, Tiffany recently welcomed fellow Girls' Generation member and "bae" YoonA to the "wonderful world of social media," tagging YoonA on the post for all fans to follow.

This is probably the best gift the female idol could have given to her fans in celebration of Choosuk.

YoonA currently has 547k followers in less than 24 hours since she's created her account.

Thank you everyone for sending in the tip!
