Hours after the happy news broke, Emmett took to Instagram to congratulate and possibly take credit for the newly engaged couple's first meeting.
He shared a picture of himself standing next to the self-proclaimed "twin flames," and wrote, "Where it all began, congrats to @meganfox @machinegunkelly so happy for you both. True love and True friends."
The post seems awkward given the tense history among the trio.
The drama started back when Fox announced she was bailing on the premiere of the movie in question, Midnight In The Switchgrass, citing concerns with Los Angeles' COVID-19 spike.
Emmet's fiancée at the time, Lala Kent, then appeared to shade the actress by posting and later deleting a photo of herself standing in front of the movie's poster, strategically blocking Fox's and her name.
The situation prompted fans to notice that neither Megan nor MGK (real name Colson Baker) had promoted the film despite starring in it.
Then on premiere day, the musician tweeted, "If I didn't talk or tweet about a movie I'm barely in it's because it's [trash emoji]."
Not only that, but both he and Megan refused to discuss the movie in any interviews.
As Radar previously reported, MGK popped the question to Fox and announced that she had said "of course" in a social media post on Wednesday.
The Hollywood lovebirds posted a video showing the Till I Die singer getting down on one knee in Puerto Rico and pulling out a black box containing a specially designed sparkler.
Megan revealed that the tree where the special moment took place held significant meaning to the couple.
"In July of 2020, we sat under this banyan tree we asked for magic," she wrote. "We were oblivious to the pain we would face together in such a short, frenetic period of time. Unaware of the work and sacrifices the relationship would require from us but intoxicated off of the love. And the karma."
The actress added, "Somehow a year and a half later, having walked through hell together, and having laughed more than I ever imagined possible, he asked me to marry him."
