MGK Gets Nekkid For Stoner Movie Starring Megan Fox & Pete Davidson

Machine Gun Kelly has just made a stoner movie, called "Good Mourning" that is playing in select theatres and on-demand. Starring the likes of MGK, Mod Sun, Becky G, Megan Fox, and featuring cameos from Avril Lavigne, Dennis Rodman, Danny Trejo, and Snoop Dogg, this is one comedy that MGK is happy to lose his pants for.

His latest Instagram post is him standing naked, with a cloth held over his family jewels. Mod Sun called it his "greatest post ever." Here go all the juicy, smoky details.

Well, okay, not really. Fox is not dumping her beautiful boy, but a garbled text from her is what set the movie in motion.

According to the Daily Beast, Mod Sun revealed that the movie was inspired by a text sent by Megan Fox, which MGK interpreted as her dumping him. The two had only been dating for a short time and Megan had to fly to a remote location in Europe, from where she sent him a text that got a little mixed up.

Considering they have matching voodoo dolls tats on their ring fingers, there's no danger of Fox dumping him, yet.

Mod said, "He started spiraling and he hit me up and he’s like, 'Yo, I just need to keep my mind off this, I don't know what's going on, I can’t tell if we’re breaking up or we’re done. Let’s write a movie about it.' And me, I was just being a really good friend, so I was like, ‘Yeah dude, whatever to keep your mind off this.'"

And so MGK and Mod Sun wrote the movie, which is about London Clash, a fictional TV star who spirals on the day of a Batman audition when he wakes up to a "presumed" breakup text from his famous actress girlfriend. Played by Becky G, the text sent by the actress, Apple, reads: “Good mourning. I wish I didn’t have to do this through text.”

In any respectable or rather, the opposite stoner movie, any bad news is followed by the next logical step, to light up. Movies like "Half Baked", "Pineapple Express", "Dude, Where’s My Car?", and, of course, "Dazed and Confused" taught us just that.

"Good Mourning" is no different. Once the friends light up and get high, "Hangover" like things happen. A house fire, getting stitched up by a stalker, parties, getting arrested, and even a scene where an urn of human ashes is replaced with, well, other ashes. There's Amber Rose and Tommy Lee in the brouhaha as well, and even Pete Davidson is around.

Davidson is playing Berry, a hotel valet who desperately wants to be part of London’s posse and the former SNL comedian steals every scene with his improv. Says Mod, “That is the beauty of working with true comedians."

Funnily enough, despite the hot and heavy romance that MGK and Megan Fox have going on, with the blood-drinking and the tongue touching and the tattoos (and the voodoo dolls?), the movie shows them playing roommates. "Good Mourning" has Fox playing his weed-loving roommate, Olive, with pink hair.

While you digest that, here's MGK, in all his naked, tattoos-covered-up glory...

In his Sunday night performance at the Billboard Music Awards, MGK hit the stage and dedicated his song, "Twin Flame" to his girl, Megan Fox. Before belting out the number, he spoke onstage, saying, "I wrote this song for my wife" before adding: "And this is for our unborn child."

So does this mean the couple has already secretly wed? Or are they pregnant?

Considering they have imbibed each other's life force, as in blood, the speculation is not all that hard to imagine. The singer, 32, also spoke to ET on the red carpet and admitted he played it, especially for her, considering on Monday, Megan Fox turned 37.

MGK said, "It's like it's all meant to be. There's like super special secret meaning to the song as well. So I'm sure I will be [emotional], but I can't cry and f— up this eyeliner." MGK tweeted about the performance after the BBMA, noting that it "broke my heart to sing the end of that song."

In the following tweet, he also mentioned, "I recorded twin flame 2 years ago today, the second half came a year later. beautifully serendipitous getting to sing it for you tonight."
