Singer-songwriter Halsey extended heartfelt birthday wishes to BTS’ Suga, who has turned a year older on Wednesday.

Halsey, who has been a collaborator and good friend of Suga, took to her Instagram Story and shared a strip of three black and white pictures in which Suga could be seen cuddling her son Ender.

She captioned the post as, “happy bday twin,” and dropped a black heart emoticon.
