Back in August, Eminem dropped his tenth studio album.
The record itself was a surprise -- arriving with no prior announcement or promotion -- but the real shocker was the lyrical content on some of the songs.
Recent years have seen the emergence of a kinder, gentler Eminem, and many fans were taken aback by the rapper's verbal assault on some of this generation's most popular hip hop artists.
The list of victims included Drake, Lil Yachty, Lil Pump, Machine Gun Kelly, Lil Xan, and Tyler the Creator.
Some of Em's younger fans found themselves with divided loyalties as the elder statesman of rap laid waste to some of their next-gen favorites.
And it seems one of those conflicted stans is none other than Justin Bieber.
Though hip hop isn't exactly the first genre that springs to mind when one thinks of the Biebs, Justin has been vocal about his love of rap over the years.
And for some reason, he chose this week to weigh in on Kamikaze -- which came out eight months ago.
"I just like Em’s flow but don’t like that he’s dissing new rappers," Bieber wrote in a recent Instagram Story.
"I like the new generation of rap he just doesn’t understand it."
Obviously, Justin is really poking the bear here, but it seems unlikely that Em will bother to respond.
The question now is -- why did Justin feel the need to enter this controversy so long after it began?
It's possible he's just offering his opinion of a rap legend's latest release.
But fans think there might be something more going on here.
The most pitiable victim of Em's industry-wide roasting was Machine Gun Kelly, who was savaged by the OG blonde emcee in numerous scathing bars.
"Next time you don’t gotta use Tech N9ne if you wanna come at me with a sub-machine gun / And I’m talking to you but you already know who the f**k you are, Kelly,"
"I don’t use sublims and sure as f--k don’t sneak-diss/But keep commenting on my daughter Hailie."
Yes, Kelly commented on the appearance of Eminem's daughter, and while his remarks were complimentary, they still didn't sit well with Slim Shady.
The case Eminem vs. Machine Gun Kelly was decided on Twitter last summer, with the majority of hip hop fans agreeing that Em was the obvious victor.
But it seems that Bieber doesn't agree with that assessment -- a fact that's led many to the assumption that the singer recently struck up a friendship with MGK.
Could a collaboration be on the way?
We hope so -- not because we're looking forward to such a song, but because we'd hate to think Justin did something as stupid as antagonizing Eminem for no reason.
