It's been a while since the whole Eminem vs Machine Gun Kelly saga, leaving us free to concentrate on other unexpected celebrity beef wars (hello, Justin Bieber vs Tom Cruise).
But like a crap song that won't get out of your head, looks like they just don't want to let this one die - well, at least Machine Gun Kelly doesn't anyway.
On the 29-year-old rapper's fourth album Hotel Diablo - released 5 July - it would appear he referenced his beef with Eminem on new track 'Floor 13'.
Check out some of the lyrics and see for yourself: "I just spent too many minutes watching little videos of s***ty wannabe rappers dissing me/I just spent the winter living after someone tried to send a kill shot missing me."
On a separate verse he raps: "One legend that tried to f**k with me and got the venom."
Seems legit, right? The fans certainly seem to think so and have been flocking to Twitter to share their thoughts on MGK's biting lyrics, with many offering support to Marshall Mathers.
"Machine gun kelly's new album is great tbh, but he needs to admit that eminem killed him lyrically and stop sub dissing him to get attention," wrote one user, while another said, "Machine gun kelly still dissing eminem like haven't you gotten enough clout."
A third chimed in with the following: "Machine Gun Kelly could be good at music but it's just so cringey when he talks about Eminem at this point.
"We get it your the 'Gunner' and your mad at him or whatever and shit but it doesn't make good music and it doesn't make anyone wanna be on ur side when u make bad music."
For those who weren't following the first time round, the two rappers were embroiled in an ongoing battle in autumn last year after Eminem dropped his diss-album Kamikaze, in which he fired shots as numerous people, one of them being MGK for comments he'd made about Em's daughter Hayley back in 2012.
What resulted was a social media war of words, two massively viral diss tracks - Em's 'Killshot' and MGK's 'Rap Devil' - and some rather speculative fan theories.
Whether Eminem responds to these latest lyrics is yet to be seen, but MGK's got to confirm or deny whether the lyrics are about the rapper first.
It seems doubtful this is enough to reignite their fight though - the pair have fired a couple of weak shots at each other online since it all kicked off, but on the whole it seems like this publicity stunt, ahem, sorry, celebrity feud is done and dusted. I could be proven wrong though, only time will tell.
