Megan Fox’s Ex Brian Austin Green Has Stern Words for Machine Gun Kelly After Breakup

Megan Fox’s ex-husband Brian Austin Green spoke out about the pregnant Transformers star’s split from fiancé Machine Gun Kelly in a Dec. 12 interview. Find out what he had to say.

Brian Austin Green is firmly in his ex-wife Megan Fox’s corner.

While the Beverly Hills 90210 alum had “no idea” about the pregnant Transformers star’s split from fiancé Machine Gun Kelly, he had a strongly-worded message for the dad-to-be.

“He’s in his 30s, isn’t he?” Brian said of MGK, 34, in a Dec. 12 interview with TMZ. “In your 30s, f–k. Grow up. Like, she’s pregnant.”

Despite his passionate reaction, Brian—who shares kids Noah, 12, Bodhi, 10, and Journey, 8, with Megan as well as 2-year-old son Zane with dancer Sharna Burgess—expressed empathy for his ex.

“I just want the best for her,” the 51-year-old shared. “I’m heartbroken about it, because I know she’s been so excited and the kids are so excited for life and the change and all of that.”

The Anger Management star also had an optimistic outlook for his blended family.

“I hope that the best outcome that could possibly happen, happens,” he continued. “For her, for the baby and for our kids.”

Megan and MGK—who shares 15-year-old daughter Casie with ex Emma Cannon—first began dating in 2020 and got engaged two years later. In 2023, the Jennifer’s Body star shared that she and the “Twin Flame” singer had tragically suffered a miscarriage.

“I’ve never been through anything like that in my life,” she told Good Morning America at the time. “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?”

While the couple went on to announce the impending arrival of their first child together Nov. 11, multiple outlets reported the two parted ways just one month later.

And although neither star has commented on the alleged split, Megan’s Subservience costar Michele Morrone quickly shut down rumors that he’d taken up a romance with her.

“Any accusations beyond a work friendship are simply untrue,” Michele’s rep told E! News Dec. 10. “They filmed a movie together a year ago. Michele is currently in Italy filming another project.”
