Sunny
Sunny (써니), born Susan Soonkyu Lee (이순규) on May 15, 1989 in Orange County, California, holds a unique position in K-pop as both a celebrated performer and a member of its most powerful family. The niece of SM Entertainment founder Lee Soo Man, she earned her place in the industry entirely on her own terms as a member of Girls' Generation (소녀시대), one of the most iconic girl groups in K-pop history.
After joining SM Entertainment as a trainee, Sunny debuted with Girls' Generation in 2007. The group defined the second generation of K-pop, topping charts across Asia and reaching audiences far beyond Korea. Within the group, Sunny became known for her powerful vocals, comedic personality, and hosting abilities -- building a parallel career in variety television that kept her visible even during quiet release periods.
On April 9, 2025, A2O Entertainment -- the label founded by her uncle Lee Soo Man after his departure from SM -- confirmed Sunny had signed with them, where she works as a producer supporting trainees alongside producer Yoo Young Jin. She appeared at SMTOWN: The Culture, The Future in 2025, reconnecting with fans on a large stage for the first time in years.
Sunny brings both institutional K-pop lineage and genuine creative investment to everything she touches.
