SAN FRANCISCO (AP) — K-pop superstar Rosé said Friday at a mental health awareness event hosted by first lady Jill Biden that it's important for the world to understand that famous people grapple with emotional struggles, too. “I think that would be very great, for everybody who works under the public eye," she said, perched on a slate gray couch at the Apple Park campus in Cupertino after hugging the first lady, who thanked her for coming. Rosé, a part of the supergroup BLACKPINK, said having a large social media following makes her feel vulnerable, particularly when people are critical.
