Machine Gun Kelly goes fully nude to promote ‘Good Mourning’

Machine Gun Kelly is baring it all for the sake of his new movie.

The “Bloody Valentine” rocker, 32, posed fully nude with shared the naked snap via his Instagram on Saturday – all to promote his stoner comedy, “Good Mourning.”

“i did 5 whole sit ups (and 200 blunts) to prep for my role in Good Mourning. 💪🏼🎬 ,” he captioned the NSFW shot, which showed him strategically censoring his manhood with a towel.

The heavily tattooed musician’s ink was noticeably missing from the snap, having been covered for the film.

“This is your greatest post yet,” pal Mod Sun joked in the comments section.

MGK (real name: Colson Baker) previously revealed that the film was based on a real text message he received from fiancée Megan Fox.

At the time, he thought the “Jennifer’s Body” star was breaking up with him.

MGK’s fiancée, Megan Fox, also stars in the stoner comedy.

“I wrote the movie for her because she was unknowingly the cause of the spiral,” MGK told Extra ahead of the movie’s release on May 20.

“[My character] spirals over a text that he doesn’t really understand and he can’t get a hold of her, and that was what was happening to me.”

The rocker previously revealed that the script was inspired by a text from Fox.

MGK also shared how Fox, 36, reacted to the script, telling the outlet, “She was like, ‘This is what you were thinking the whole time?’”

The “Emo Girl” singer’s latest wild antic comes just one week after he and Fox – who have been engaged since January – made headlines at the Billboard Music Awards 2022.

Ahead of the awards show, Fox shared a screenshot of a text convo between her and stylist Maeve Reilly, in which she revealed she and her beau cut a hole in the crotch area of her skintight blue jumpsuit so the two could have sex.
