Charlie Puth Continues To Diss Justin Bieber

(Radio.com) What is Charlie Puth's deal with Justin Bieber? Remember a few months ago he yelled, "f you Justin Bieber!" while he was on stage? He later apologized and sent out a series of tweets giving him love but something didn't seem right.

Now it appears that Puth is throwing a little shade at the Biebs again. Justin took to Instagram to give a little song writing advice, saying, "If u write music take notes from the greatest writer to ever do it Jason Boyd aka Poo bear."

Although Justin was giving love to his boy, and Purpose collaborator, Charlie apparently disagreed because he sent out a tweet saying "If you write music, write from the heart. You don't take notes, you hear them." Check out the posts here.
