About Megan Fox’s relationship with Machine Gun Kelly

Megan Fox and Machine Gun Kelly met and got to know each other when the two were shooting the film Midnight in the Switchgrass. This was in March 2020, just a few weeks before the film's production was halted due to the coronavirus pandemic.

Speaking to GQ Style about her encounter with Kelly at the film set, Fox said,

“It was obvious from second one what it was going to be…but we didn’t hook up right away.”

Describing her emotional state at the time she met Kelly, Fox, during the same interview with GQ Style, said,

“But I did not anticipate walking right into my soulmate like that. I was obviously over the way I had been living, and those paths lined up, those doors opened.”

Sharing how her relationship with Kelly changed her, Fox shared,

“I think I had either put myself in, or allowed other people to put me in, this weird box that didn’t quite fit me, where I hadn’t lived my own life as myself for a really long time… the parts of me that were always eccentric or strange and didn’t belong within my own family unit or within Hollywood.”

Megan Fox and Machine Gun Kelly appeared together as a couple in a public event for the first time in November 2020 at the American Music Awards ceremony, per People Magazine. The same report noted that Fox officially filed for divorce three days after their first public appearance with Kelly.

Another report by People Magazine notes that, as per an unnamed source, Fox had even introduced her children to Kelly by then. As per the news outlet, the source said,

“He recently met her kids for the first time. Megan thought it was a natural step, since they are getting more serious.”

According to Bustle, Fox and Kelly got engaged in January 2022, when the latter proposed to the Teenage Mutant Ninja Turtles actress with a diamond ring.

Fox also announced her engagement to Kelly in a social media post, sharing that she had said yes to Kelly’s proposal. As per the report by Bustle, Fox also shared in her post that to celebrate the engagement, the couple drank each other’s blood. The news outlet notes that Fox has now deleted the post.

Speculations about Fox and Kelly’s supposed break-up flared up when the actress deleted all her photographs with Kelly from her social media in early 2023, as per the report by Bustle. However, the couple were seen together in public when they attended the red carpet launch of Sports Illustrated Weekly’s Swimsuit Issue on March 23.

On November 23, Megan Fox opened up to People Magazine about suffering a miscarriage from a previous pregnancy. Describing the ordeal that she and Kelly went through, Fox told People Magazine,

"I’ve never been through anything like that in my life. I have three kids, so it was very difficult for both of us and it sent us on a very wild journey together and separately… trying to navigate, ‘What does this mean?’ and ‘Why did this happen?’”
