As Girls' Generation is pretty much known for their bond and sisterly love, Yuri proved just that by showing her support for member Taeyeon on her solo album.

The Black Pearl took it to Instagram to tell followers and fans to support the Girls' Generation leader as Taeyeon released her first solo album through various music websites.

"Taeyeon, I sincerely congratulate you," Yuri captioned her photo of a screenshot of her streaming her album. "Please sing for a long, long time. Everyone, please take good care of my Taeyeon."

The album includes the title song "I" and other songs such as "U R," "Tell Me First," "Stress," etc. The title song "I" reveals Taeyeon's musical transformation. 

Taeyeon will hold her first debut stage on Mnet "M! Countdown" on Thursday.
