Normally, you wouldn't associate Justin Bieber and Ed Sheeran. Aside from them collaboration on Justin's song, "Love Yourself," they're in very different social circles.
Justin spoke out on his friendship with ed, and revealed that they're not exactly close. He said, "me and Ed aren't super close, but he's someone who I consider a friend and I really appreciate his music. I appreciate who he is as a person. He's an inspiration to a lot of young people -- he makes awesome music that people are inspired by and that people laugh to, cry to and I think it's important in music to have those people who bring the emotion out of you."
Even though they aren't besties, it doesn't mean that Justin isn't looking out for Ed. Justin offered his own advice on fame to Ed once, but revealing that he hopes to keep an eye on Ed, and "make sure he doesn't do something stupid to mess it all up."
Thats pretty solid advice from someone like Justin, and we are almost certain Ed won't be doing anything to jeopardize his career, but it's great that the advice was given!
