United Kingdom, June 9 -- Machine Gun Kelly turned yellow after getting "really sick" due to his blackout tattoo.

The Lonely Road hitmaker debuted his dramatic body art back in 2024, but has now revealed it had a huge impact on his health after ignoring tattoo artist ROXX's advice to spend two years working on the look.

He told Billboard Canada: "She warned me that it was going to be near impossible, even from a pain tolerance standpoint. I said, 'Yeah, we got two months.'

"After the first week, we hit my lymph nodes around my armpits and shoulders, and I got really sick.

"My skin was turning yellow. I wasn't able to sleep. I stopped being able to move certain parts of my upper body."
