IU wowed fans with her new hairstyle -- a blonde bob.

The singer was spotted Saturday at a concert held by Posco, where she was one of the performers, along with Shin Seol-hee and Choi Baek-ho.

During the event, IU said, “I dyed my hair because of a shoot. Since my hair became so damaged by it, I will have to wait for a long time before I can dye it dark again.”

The singer previously went blonde for her “Modern Times” album in 2014.

Later this month, IU will release her new album “A Flower Bookmark Two,” the singer’s second cover EP that follows the first one released in May 2014. The new album comes five months after her fourth full-length album “Palette.”
