Girls’ Generation’s Taeyeon released a selfie that she took with Tiffany and Seohyun on Monday, a day before TaeTiSeo’s new album release.

“If you knew anything would come up, it would be us, thanksta!” Taeyeon wrote on her Instagram.

The trio, the Girls’ Generation sub-unit dubbed TaeTiSeo, are to drop their second EP “Holler” on Sept. 16, more than two years after the group unveiled its debut EP “Twinkle.”

The group will hold a showcase of its latest EP on the same day at Seoul Olympic Park’s Woori Financial Art Hall.
