Post Malone would take part in Justin Bieber and Hailey Baldwin's wedding if asked. Ambushed by the TMZ cameras, Post was asked if he would perform at the wedding. He said, "F-yeah, for free. I'll be the flower boy...or the ring bearer." Post also said about Bieber, "He's very happy. I love to see my boy happy."
If you could choose ONE artist to perform at the wedding who would it be?
