Pop singer Justin Bieber had some words for veteran rapper Eminem and wants him to stop dissing the new wave rappers.

"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," he wrote on his Instagram story after posting a screenshot of 'Kamikaze' opening track "The Ringer." 

In "The Ringer" Em takes swipes at several young rappers:

"I can see why people like Lil' Yachty, but not me though

Not even dissin', it just ain't for me

All I am simply is just an emcee

Maybe "Stan" just isn't your cup of tea

Maybe your cup's full of syrup and lean," he spits.

"I'd just be like everyone else in the f*cking industry

Especially an effing Recovery clone of me

So finger-bang, chicken wang, MGK, Iggy 'Zae

Lil' Pump, Lil' Xan imitate Lil' Wayne

I should aim at everybody in the game, pick a name

I'm fed up with being humble" he also raps on the track.

We're not sure what made Justin call Eminem out when he did. Kamikaze dropped in August 2018 - almost nine months ago. He's a little late to the party on this one.
