Justin Bieber might have just reignited his rumored feud with Eminem--all with just one Instagram Story.


The 25-year-old singer took to social media earlier this week to take a direct hit at the veteran rapper, explaining how he doesn't like Em's viewpoints on music. Justin posted a screenshot of the rapper's song "Kamikaze," then posted another IG Story explaining why he was listening to it.


"I just like Em's flow but don't like that he's dissing new rappers," Justin wrote. "I like the new generation of rap he just doesn't understand it." While we're not sure which artists Justin is referring to here, Eminem famously has a laundry list of stars he's called out through his music. His numerous critiques of young rappers include a homophobic bash of Tyler, the Creator, a diss track about Machine Gun Kelly, and lines about Lil Pump and Lil Yachty, to name a few.


Justin and Eminem also have history, as most recently, the latter put out a freestyle called "Kick Off" in Dec. 2018 which name-dropped both the "Sorry" singer and Ariana Grande, among others.


We don't think Justin was trying to start something by posting this Instagram Story, but we can bet Eminem will be calling him out in some form through new music.
