As the hip-hop world patiently waits on Eminem's response to Machine Gun Kelly's scathing "Rap devil," one of Em's longtime friends and collaborators in fellow D12 member Bizarre decided to chime in with his thoughts regarding the ongoing feud -- and Slim Shady's possible imminent retaliation -- on Monday (Sept. 3). 

Biz posted a near-minute long selfie video, and was actually highly complimentary of MGK's rapping ability on the track dissing his close friend. "I think it was good. I think this is the best I ever heard Mr. Kelly rap in his life. I think he stayed up all night and wrote the best possible bars he possibly could, and I think it’s good for hip-hop," he admits.

However, the Detroit native made sure to let Kelly know to be prepared for the lyrical assault he has coming his way courtesy of Eminem."But boy, the repercussions... oof. The boy gonna do you something nasty. Y'all better stop playing with that boy," the 42-year-old solemnly warns.
