Machine Gun Kelly clearly can't resist firing shots at Eminem. Last night (Feb. 20), MGK tweeted his reaction to Em's latest MGK diss, which came during a performance in Australia earlier this week. For his response, the rapper claimed that Eminem was right to skip out on performing his MGK diss "Killshot" because the song is, in his mind, bad.

"Ay @Eminem u made the right decision not dropping that weak ass song in concert and putting everyone to sleep. 😂👎🏽🚮😈 #RapDevil," Kelly tweeted.

The sarcastic tweet was posted hours after Marshall Mathers, who served as executive producer of the battle rap-inspired film Bodied, refused to give MGK any attention on stage by performing the diss song aimed at him. Em closed out the show by reassuring the crowd that he still doesn't like MGK.

“I would but I can’t give that cocksucker any more light,” Em told the audience.

Eminem and MGK's feud has been on-going since 2012 back when a young Kelly tweeted about Eminem's daughter. Their beef exploded when Em called out MGK in his song "Not Alike" off his Kamikaze album. Kelly responded with "Rap Devil," which prompted Eminem to go off on him in "Killshot." Before his concert down under, Em hadn't mentioned MGK at all even after the rapper fired one last shot at him before the end of 2018.
