Cardi B had a big night at her first ever Grammys. She was nominated for two awards, though sadly didn't win, while her live performance with with Bruno Mars was a highlight. Backstage though, the "Bodak Yellow" rapper spent her time meeting some unlikely heroes. Step forward Bono, frontman of U2. Cardi shared a fun video on Instagram of a note he passed her ("You're the biggest thing in our House in Ireland") and her reaction was priceless. Check out the clip above.
