Last month Lizzo and BTS attended a Harry Styles show together, and clips emerged of Lizzo singing "What Makes You Beautiful" with BTS member V.

After calling BTS her "besties", she's wished V a happy birthday on Twitter. As well as sharing some fan-made artwork, Lizzo wrote, "#HAPPYVDAY somebody made this and it’s soooo cute! Happy bday V."

BTS' RM and Jimin used the group's official Twitter account to wish V a happy birthday, and shared some images from over the years.

On Christmas eve (24 December) V unveiled his Our Beloved Summer solo song "Christmas Tree".
