Aug. 2 (UPI) -- South Korean girl group Girls' Generation shared a new teaser for Holiday Night featuring Sunny this week.
The 28-year-old American singer reflects on the band's success in the promo for the album, which is scheduled to debut Friday.
"They were all really chaotic and we were very nervous at first," she recalled of the group's early performances. "We've worked hard until now, but I think we've gotten to this point because we've enjoyed it."
Girls' Generation previously released teasers for Taeyeon, Tiffany, Hyoyeon, Yuri, Sooyoung, Yoona and Seohyun. Yuri said last week that she's doing "fine" after injuring her leg ahead of the album's big release.
"I pulled a ligament in my leg but you don't need to worry that much. Everything's gonna be fine cause I've got Sone," she wrote on Instagram, referencing the group's fans. "Thank you for being with me all the time~!"
The Chosun Ilbo reported in July that Holiday Night is meant to celebrate the 10-year anniversary of Girls' Generation's debut. The K-pop stars will promote the album at a fan event Saturday in Seoul.
