A lot of celebrities are showing their support for Seohyun and her musical, 'Gone with the Wind'!

Most recently, her fellow Girls' Generation members Yuri and Sooyoung went to watch her performance after which the three took a picture backstage!  Seohyun uploaded the shot onto her Instagram on February 9.

She wrote, "Sooyoung and Yuri came to the musical to show their support not too long ago.  Their endless compliments and support gave me a lot of strength.  Thank you so, so much."
