Iggy Azeala and Eminem have a history: Iggy criticized Em for including her in rape lyrics on the 2014 Shady XV comp album.

Iggy's back after Eminem after he mentioned her again, this time on his brand new Machine Gun Kelly diss "Killshot"

You ain't never made a list next to no Biggie, no Jay
Next to Taylor Swift and that Iggy ho, you about to really blow
Kelly, they'll be putting your name
Next to Ja, next to Benzino—die, motherfucker!

Here how Iggy responded to that on Twitter:

Diss songs shouldn’t be filled with celebrity name drops to pad out lazy bars.

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.

Iam beyond prepared to be trolled for this opinion.
Hahahahaha.

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. 🤷‍♀️

Does Iggy have a point?
