Machine Gun Kelly disses Eminem live on stage in the wake of 'Killshot'

In rap terms, there's not much which inspires as much self-righteous anger as diss tracks. Hip-hop seems to actively encourage intense rivalries between artists, and many feuds have since become legendary. Although they're often confrontational, profanity-laden and violent, diss tracks have produced some really amazing music in the past, like "Hit 'Em Up" by Tupac, or "Takeover" by Jay Z, for examples.

The most recent diss track comes courtesy of Eminem, off the back of the release of his new album "Kamikaze." In "Killshot", Eminem attacks his new nemesis Machine Gun Kelly, who made an enemy of him after making some pretty NSFW comments about his daughter. In the album, Slim stated: "And I'm talkin' to you, but you already know who the f**k you are, Kelly/I don't use sublimes and sure as f**k don't sneak-diss/But keep commenting on my daughter Hailie."

Slim's track has already garnered 56 million views on YouTube, as well as commercial success and critical acclaim, and now many fans are declaring that Machine Gun Kelly's career is effectively over as a result of the barbs thrown by Shady. However, now video footage seems to show him making a major clap-back.

On Sunday night Kelly took to Instagram with photos of himself performing with a "Kill Shot" cover T-shirt. He could also be seen gesturing as though he was intending on firing a gun, with the audience behind him mimicking. Kelly captioned the snap: "He missed, #legshot #rapdevilstillNUMBERONE, #letstalkaboutit."

Then, in a video of a performance at the Amway Center in Orlando, Kelly can be heard screaming "F**k Marshall Mathers" as he opened the set with an anti-Eminem rap. At one point he even took a pot shot at his age, claiming: "The real Slim Shady can't stand up."

Recently, fellow-musician Iggy Azalea made it clear that she supported Kelly, and criticised Eminem's songwriting abilities. Taking to Twitter she stated: "Diss songs shouldn’t be filled with celebrity name drops to pad out lazy bars ... Also let’s talk about why it’s lazy now; but wasn’t in the earlier work. The earlier stuff was crazy, twisted and creative. This stuff feels more like picking names that fit easily into a rhyme scheme. And that’s my unbiased opinion from a girl that watched this guys set and sung the words in the crowd. I’d think it regardless. One of the greatest to do it, I’m NOT in dispute about that. But I do think the name dropping thing has become a crotch. [sic]"

Yeah, it's fair to say that the longer the feud goes on, the more bitter and caustic the atmosphere is going to become. We can only hope that these two dudes bury the hatchet and settle their differences, but somehow, what with their egos being the sizes they are, I don't think that's going to happen anytime soon, do you?
