Eminem has reignited his beef with Machine Gun Kelly after ending his rap career with Killshot

"Before you die let's see who can out-petty who / With your corny lines (Slim you're old) / Ow, Kelly, ooh, but I'm 45 and I'm still outselling you."

Eminem really did not hold back when he lashed out at Machine Gun Kelly with his 2018 track 'Killshot', and for a lot of people that was the final blow in a long-standing beef between the pair.

But five years on, Eminem has just dropped a new album and it seems like he's coming for Kelly all over again.

'The Death of Slim Shady (Coup de Grâce)' arrived today (12 July) after Em gave us a taste of his new tracks with the singles 'Houdini' and 'Tobey'.

The album, which he promoted with a picture of a gravestone, focuses on Eminem's Slim Shady alter-ego and draws attention to some of the controversies he's been involved with in the past, before the rapper indicates that he's leaving that part of himself behind.

That's not to say he's forgiving and forgetting everything that came before, though.

In his track 'Bad One', Em makes reference to his beef with Kelly as he sings: "But I gotta keep going Tyson on Kelly / I bodied him twice and already / That little motherf***er's back throwing subs like a food fight at the deli."

The track officially reignites the feud between the two rappers, and fans are loving it.

In a Reddit thread about 'Bad One', one fan commented: "Mgk gettin buried again is hilarious [sic]."

Another wrote: "That Mgk diss was slick on “Bad One” I can’t even lie. Eminem will never stop beating on him."

Others praised the song as a whole, with one fan describing it as 'fire'.

The release of 'Bad One' now means that the beef between Kelly and Eminem has officially been ongoing for more than a decade.

Many fans believe the conflict kicked off in 2012, when Kelly posted a since-deleted tweet in which he said Eminem's daughter Hailie Jade was 'hot'.

Hailie might be grown up and married now, but at the time she was just 16 years old.

Em appeared to hold on to his anger about that as he made a reference to Kelly's comment six years later, in his track 'Not Alike'.

Em rapped: "I'm talkin' to you, but you already know who the f**k you are, Kelly...I don't use sublime and sure as f**k don't sneak-diss...But keep commenting on my daughter Hailie."

However, Eminem has actually denied the beef started with Kelly's comments, instead later claiming Kelly had implied Eminem was 'trying to hinder his career'.

For his part, Kelly has hit back with tracks like 'Rap Devil' - a flipped reference to Eminem's 'Rap God'.
