Machine Gun Kelly Shares a Video of the Grueling Process Behind His 'Most Painful' Blackout Tattoo

Machine Gun Kelly is giving fans an up-close and personal look into his most intense tattoo experience yet.

In February, the rapper and singer-songwriter, 33, debuted a massive blackout tattoo that spans across his upper torso and both arms, covering most of his previous tattoos. “For spiritual purposes only,” he captioned an Instagram post showing off his new ink, which he shared required 44 needles to complete. 

On Monday, MGK shared an Instagram video documenting the grueling process.

“Today starts the day that I start the physical change of my body,” he says at the start of the video with his old ink still visible. “We’ll see what this turns out to be.”

Over the course of multiple weeks, the musician sat for lengthy sessions of tattooing, which took a toll on his body. In his video, MGK’s arms can be seen dripping with blood and at one point, his elbow becomes swollen.

“This is the most painful s--- I’ve ever experienced in my life,” he remarks.

At the end of the video, MGK is seen wearing an oxygen mask while sitting in a hyperbaric oxygen chamber, which he claims is intended to help his body “heal faster.”

The singer, whose real name is Colson Baker, received a flood of "likes" and comments on Instagram after first revealing the new tattoo in February. At the time, his tattoo artist, R O X X, also took to social media to share his latest work.

"Made some art with @machinegunkelly Never met a tougher one," the artist captioned the photo.

MGK’s fiancé, Megan Fox, shared her thoughts on the shocking tattoo transformation during an appearance on Alex Cooper's Call Her Daddy podcast in March.

The actress, 37, said she thought the tattoo was “really elegant” and noted that MGK has a “special story” that is only his to tell.

"But the relationship with the tattoos that he had was very conflicted emotionally, whatever they represented — and I don't actually know — but he didn't like to revisit those memories of some of the tattoos that he had and he wanted to get rid of them," Fox told Cooper.

"It's like an elevated version of all those tattoos that were pieced together," Fox continued. "I think it's really elegant and it's kind of ahead of its time. I think in 10 years it'll be a trend." 

The actress also revealed that MGK didn’t go under anesthesia for the tattoo and said she couldn’t imagine how he “endured that level of pain.”
