Justin Bieber squares up to Eminem: 'He doesn't understand' rap anymore

Justin Bieber isn't a fan of Eminem's infamous diss tracks, but he may well be the subject of one after his latest comments on Instagram.

Bieber posted a screenshot showing he was listening to 'The Ringer', a song from Eminem's latest album Kamikaze, on which he takes aim at a raft of rappers.

"I just like Em's flow but don't like that he's dissing new rappers," Bieber wrote.

"I like the new generation of rap, he just doesn't understand it."

Some of the targets on the album include artists like Lil Yachty, Machine Gun Kelly, Joe Budden, Lil Xan and Lil Pump, all of who were actually pleased to be mentioned by Slim Shady.

'Not Alike', a track dedicated to dissing Machine Gun Kelly, ignited a vicious feud between the two rappers. MGK responded with 'Rap Devil', before Eminem returned fire with 'Killshot'.

"Younger me? No, you're the whack me, it's funny but so true - I'd rather be 80-year-old me than 20-year-old you," Eminem raps about MGK in the song.

"My biggest flops are your greatest hits... as I'm Shady, he's gon' have to live in my shadow."

Now it appears Bieber could be next in Eminem's crosshairs, although there's evidence to suggest the pair have been on good terms in the past.

In 2017, Bieber posted a throwback snap with the 'Lose Yourself' hit maker, and reportedly once covered two of his songs during a performance in a London nightclub.
