Tiffany uploads mysterious post possibly hinting at new music release

Girls' Generation's Tiffany could be releasing new music soon? 

We hope so! The idol recently uploaded a mysterious Instagram post of herself posing chicly with people who could possibly be the collaborators for her next music release. The hints are all there: she tagged herself at SM, and it looks like she is sitting in a studio. These signs can only point to the single conclusion that Tiffany is working on her solo release.
