Remember Aaron Carter? The younger brother of Backstreet Boy Nick Carter? Well it turns out he’s got a little beef with Justin Bieber, and thinks he’s a serious threat to JB’s music career.

According to a report from TMZ, Aaron believes he laid out the ground work for Justin Beiber to become a superstar, and that Justin & his manager, Scooter Braun, should be worried about Aaron’s upcoming music.

Aaron apparently talks about his beef with Justin on Matt Weiss and Theo Von's upcoming "Allegedly" podcast, which drops in full tomorrow. He says the beef started back in 2015 when Bieber’s attorney said he helped Bieber avoid Aaron-esque career mistakes, which Aaron didn't appreciate very much.

Hear a snippet of Aaron talk that ish (below), and look for the full episode to air tomorrow.
