Machine Gun Kelly has painted his tongue black for the Billboard awards - as you do. Watch him do it below:
The musician documented his transformation on Instagram, posting a video showing him applying some sort of dye or paint to his tongue with a cotton bud.
As with many of MGK's actions, we're not exactly sure why he did it, but the black tongue for the red carpet is certainly a 'look'.
He could be seen posing with girlfriend Megan Fox prior to his trip to the Billboards, at which the 31-year-old took home awards for Top Rock Album and Top Rock Artist.
He was also nominated for Top Rock Song, but lost out to AJR's 'Bang!'.
MGK, whose real name is Colson Baker, is no stranger to making bold statements with his body - not least his plethora of tattoos.
His most recent one was a bit gruesome, to say the least.
The new tat is down the middle of the front of the American rapper's neck, and looks like a bleeding slit in the skin.
He then shared a video on his story, with the text: "Here it is. It's my birthday week, love y'all."
Previously, he revealed he wears a drop of his girlfriend Megan Fox's blood on a pendant around his neck.
On Valentine's Day, the artist - real name Colson Baker - shared a photo of himself alongside Fox.
He wrote: "I wear your blood around my neck."
For her part, Fox shared a photo collage of Kelly, with the caption: "There goes my heart/ manifest outside of my body/ draped in the towering silhouette of a most unusually handsome boy.
"Magical and haunted/ kinetic and tortured/ ethereal and dangerous/ cosmic lawless eternal creative genius/ the journey will likely be perilous/ but there is no destination without him.
"Happy valentine's day rehab barbie."
How sweet, I think.
Oddly enough, Kelly and Fox aren't the first celebrity couple who have been known to wear blood around their necks as a token of their love.
Famously, Billy Bob Thornton and Angelina Jolie used to wear necklaces with a droplet of blood contained within them as they walked down the red carpet.Featured Image Credit: Rich Fury/Getty Images for dcp
