Trending on Billboard Tetris Kelly caught up with LE SSERAFIM in Seoul, South Korea, and the girls have a “CELEBRATION” that launches them into a new era. They tease what to expect from their upcoming studio album, their experience of their first VR concert, the surprise they felt when “SPAGHETTI” popped off, working with BTS’ J-HOPE on the song, reveal where they love to go shopping, and what their next goals are! What do you think of “CELEBRATION?” Let us know in the comments! LE SSERAFIM: I don’t know how much we’re allowed to say. Tetris Kelly: You’ve got to tease a little bit, I came all the way here, so you can tell me something. You came all the way from LA to Seoul, so we feel like we should share something, even if it’s just a little.  Well it’s a celebration apparently. I’m hanging out with the girls of LE SSERAFIM, how are you doing today? We’re good! It’s so good to see you, I think it’s been a couple of years. It has been a while, and now I have to come to Seoul to see you, how about that?…
