Justin Bieber has slammed Eminem for his attitude towards modern rap music, claiming that the 46-year-old rapper simply "doesn’t understand" the "new generation".

The 25-year-old Love Yourself singer shared a screenshot to his Instagram story showing Eminem's 2018 song The Ringer being played on his iTunes, before writing, "I just like Em’s flow but don’t like that he’s dissing new rappers. I like the new generation of rap he just doesn’t understand it."

Bieber's taking aim at Eminem seems to be a response to the latter's brutal lyrical assault directed at the current generation of rappers in his diss track, The Ringer - the opening song on his 2018 surprise album Kamikaze.

The song included references to several current rappers including Machine Gun Kelly, 21 Savage, Vince Staples, Lil Yachty, Iggy Azalea, Lil Pump, and Lil Xan.

The Lose Yourself hitmaker also slated the rappers for "mumbling" in the following lyrics: "I heard your mumbling but it’s jumbled in mumbo-jumbo/The era that I’m from will pummel you, that’s what it’s coming to."

Bieber calling out the man behind Slim Shady is nothing new though. Last year, Eminem and his feud with Machine Gun Kelly received a whole lot of media attention - mainly due to how petty and back and forth it became.

Em made his hostility toward MGK public in his Kamikaze track Not Alike, accusing Kelly of directing subliminal insults at him in a song he released in collaboration with Tech N9ne.

MGK decided to retaliate - as Em did - in the recording studio. He threw shade at the 46-year-old in his track Rap Devil (an obvious play on Eminem's song Rap God).

In response to being put on blast in Rap Devil, Eminem came out with yet another brutal diss track entitled Killshot.

While Eminem has been criticised by some for being unable to age gracefully in the world of hip-hop, he's still very much in demand. According to Buzz Angle Music, in fact, he was 2018's top-selling artist for pure album sales.

So all we can do now is wait patiently for Eminem's inevitable retaliation. Could 2019's biggest celebrity feud be in the works?
