They got Howard Stern out here interviewing K-pop stars now. Last year, the Blackpink member Rosé had a huge global hit with the Bruno Mars collaboration “APT.” Today, she showed up on The Howard Stern Show, apparently to prove her bona fides. Rosé told Stern all about leaving Australia for K-pop training camp, she played the original demo of “APT,” and performed a couple of her tracks. She also sang covers of a couple of songs that were presumably chosen to endear her to Stern’s listeners.
