It seems that Justin Bieber is a man of many talents, and one of them include 'life coach'.
According to Us Weekly, the singer dropped by Zac's LA home after partying in the famous Hollywood nightclub 1OAK, and while he was there he told Zac that he should be a bit more fussy when it comes to acting.
The source revealed that Justin told Zac to "be more selective about the roles he takes.
"Justin was very honest and kind of went in on Zac… but Zac appreciated it."
And apparently Mr Efron was so happy with JB's advice, he told his new BFF "to keep breaking boundaries.
"He was giving him life tips," the insider added.
I don't know about you, but I don't think I'd fancy Justin telling me which path to take in my career. He's not exactly the poster boy for great decisions…
