Eminem kicks off his first verse of his Machine Gun Kelly diss "Killshot" with this:

Rihanna just hit me on a text
Last night I left hickeys on her neck

That's in response to Machine Gun Kelly's Shady diss "Rap Devil," in which he suggests Em couldn't get with RiRi.

In an interview with TMZ, celebrity DJ Samantha Ronson aired out "old man" Eminem for mentioning Rihanna like that. 

"I think it's misogynistic and homophobic. He's smarter than that and he's proven that he's smarter than that. It just seems like some real, like, lazy writing. By the way, Rihanna is running an empire. She's busy. She isn't putting hickeys on your neck," Ronson said. "Why do you have to bring Rihanna into this fight? Rihanna had nothing to do with any of it. We all know Rihanna isn't kissing your neck, you fucking old man. Go back and play your video games.

You're basically calling Rihanna a whore to get back at Machine Gun Kelly and his man bun,"she continued. "The beard and the man bun, you guys should like go to a groomer together.

We'll give Ronson this, it definitely sounds like she listened to all of "Killshot".
