BLACKPINK marked the 10th anniversary of its debut on Saturday with a fan meet-and-greet at the National Museum of Korea in Seoul, but the celebration drew fan backlash over how the milestone was handled, prompting a public apology from member Jisoo. "Today is the day BLACKPINK turns 10," Jisoo said during the broadcast. Jisoo addressed the criticism directly in a message to the group's fan community, writing, "This anniversary feels like a day full of regret. Alongside the fan event, BLACKPINK and the National Museum of Korea unveiled the "Blackpink Heritage Collection," a seven-item merchandise line developed with MU:DS, the museum's official goods brand. Saturday's event marked the group's first appearance before fans in Korea since its Goyang concerts in July 2025.
