Why Pregnant Megan Fox's Ex Brian Austin Green Is "Heartbroken" Over Her Split From Machine Gun Kelly

Brian Austin Green is feeling for his family right now. 

Upon hearing the news that his ex Megan Fox—with whom he shares kids Noah, 12, Bodhi, 10, and Journey, 8—had broken up with Machine Gun Kelly before their arrival of their baby, Brian expressed disappointment. 

“That’s a shame,” he told TMZ in a video published Dec. 13, before referencing Megan’s pregnancy. “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.”

He also emphasized his frustration with Megan’s ex—whom she has been on-again-off-again dating since 2020. 

“In your 30s,” Brian added of the 34-year-old. “Like, f--k. Grow up. She’s pregnant.”

And while the Beverly Hills, 90210 star—who also shares sons Kassius, 21, with ex Vanessa Marcil, as well as Zane, 2, with wife Sharna Burgess—couldn’t contain his regret for the news, he went on to say he wants the “best” outcome for everyone involved. 

“I want the best for her,” the 51-year-old continued. “I want the best for the baby. I want the best for our kids.”

He noted, “If that’s the case, that’s a tragic situation, and I wouldn’t wish it on anybody.”

As for how he’ll feel if Megan, 38, and MGK will reignite the flame? “I hope the best outcome that could possibly happen, happens,” Brian said, “for her, for the baby and for our kids.”

For her part, Megan has not yet spoken out about her breakup with MGK, which was reported by multiple outlets Dec. 10. Meanwhile, MGK shared to his Instagram Story Dec. 12, dedicating his cover of “Last Christmas” by Wham! at NBC’s A Motown Christmas Special to a cryptic recipient. 

As he wrote alongside the clip of him covering the iconic song alongside a bandaged heart emoji, “Give it to someone special.”

News of Megan and MGK’s split comes just one month after the Confessions of a Teenage Drama Queen star announced that she and the “Bad Things” rapper are expecting a baby together.

“Nothing is ever really lost,” Megan—who experienced a miscarried in 2023—wrote in a Nov. 11 Instagram post, tagging MGK on her belly. “Welcome back.”

Brian Austin Green enjoyed a lazy morning snuggled up with kids Noah, born in 2012, Bodhi, born in 2014, and Journey, born in 2016, who he shares with ex Megan Fox.

After Brian and Megan split in 2020, the Beverly Hills, 90210 alum found love with his Dancing with the Stars pro partner Sharna Burgess. The two welcomed son Zane in 2022, and announced their engagement the following year.

Meanwhile, Machine Gun Kelly—whose real name is Colson Baker—welcomed daughter Casie with ex Emma Cannon in 2009. He went on to get engaged to Megan in 2023.

Despite her commitment to co-parenting, Megan has said it's not always a walk in the park. “It’s hard to not feel obligated to be with them all the time or to constantly feel like I’m not doing a good enough job,” she admitted to Glamour UK in 2022, “but I’m also separated from their father. So, I can only have them half of the time. That just is what it is.”

Brian's blended family includes his son Kassius, 22, whom he shares with ex Vanessa Marcil. The actor posed with Sharna and all five of his kids for a festive family photo in December 2023.

For Megan, motherhood keeps her grounded. "When I step back, I know how connected I am and I’ve always been and how present I’ve always been,” she told Sports Illustrated Swimsuit in 2023. “I see the reflection of the type of mother that I am in their eyes and in their behavior."

In 2022, the Jennifer's Body star posted a rare photo alongside the "Emo Girl" singer and his daughter, taken at his 27 Club Coffee shop in Ohio.

The hitmaker turns to his daughter for advice on his music. "I trust her opinion more than I trust my own now," he said on The Kelly Clarkson Show in 2021. "Like, she has her finger on the pulse of what's hot, or if I'm doing a song and it's the right one, she'll confirm it."

In honor of Mother's Day 2024, Brian paid a loving tribute to Sharna. "You are an incredible mother and fiancée," he wrote on Instagram, "and we all love you to death."

Megan rarely features Journey and his siblings on social media—for one very good reason. "I knew when they were very young, I wanted to try to protect them however I could, especially limiting their exposure to the internet," she told Glamour UK in 2022. "So far, we’ve done a really good job and we maintain their innocence in a lot of ways, but I know I can’t protect them forever."

Brian's golden rule for co-parenting? Picking his battles. "People make a mistake of thinking that they're gonna do things so the separation doesn't affect the kids," he told E! News in 2024. "Of course it's gonna affect the kids. The only choice you have is how it affects the kids."

Likewise, Megan makes a point not to speak ill of her kids' father around them. "I don't let anything in my energy like that when I'm around my kids," she said on The Drew Barrymore Show in 2023, "because if I don't accept and love their father, I'm rejecting a part of them, because he's a part of who they are always.

Brian snapped a pic of his brood having some fun in the sun in Malibu, captioning the Instagram post, "Great day!!"

MGK—pictured with Casie at the Kids' Choice Awards in 2019—credited his daughter with helping him get clean after she told him she knew when he was high. "That was step one for me," the musician, who has been sober since August 2023, said on the Million Dollaz Worth of Game podcast. "As a father and as a man, to be the father I wish my dad would have been, I have to break this generational curse for my kid."

Sharna has thanked Brian's kids for preparing her to be a mom. "I got to test out motherhood with these guys," she said on the Quite Frankly podcast in 2023. "I got to learn things and grow with them, about parenting and understanding kids ... and knowing, 'Oh my God, I think I can be really good at that.'"

In 2020, Brian was a celebrity contestant on The Masked Singer. "I was super excited for my kids to watch it with me," he wrote on Instagram, but "they fell asleep after 15 min."

No job is too big for the TV star and his mini-mes.

While Brian revealed he got a vasectomy eight weeks after Zane was born, that doesn't mean he couldn't have it reversed down the road. "If we have the space and the ability to, would we love to? I certainly would," Sharna said on the Oldish podcast in January. "But we do have four young kids in the home and life is very, very busy."

On March 27, 2025, Megan and MGK welcomed the newest member of their blended family: a baby girl, who arrived into the world with her own original score composed by the rocker and his musical pals including Travis Barker.

"She’s finally here," MGK exclaimed in a post on Instagram, "our little celestial seed."
