Brian Austin Green Tells MGK to ‘Grow Up’ After Musician’s Split From Megan Fox: ‘She’s Pregnant’

Brian Austin Green is firmly on the side of Megan Fox — to whom he was married from 2010 to 2022 and shares three kids with — when it comes to the actress’ rumored split from MGK this week.

While out and about Thursday (Dec. 12), the Beverly Hills, 90210 alum reacted to the news of his famous ex’s split from the musician when TMZ approached him for comment. “I didn’t even know,” he begins in a clip on the outlet’s website, throwing his head back with a big sigh.

“How old is he? He’s in his 30s, isn’t he?” Green continued after the reporter suggested that something on the “My Ex’s Best Friend” musician’s phone had sparked the breakup. “In your 30s, grow up. She’s pregnant.”

Billboard has reached out to reps for the actress and musician.

The actor’s comments come just days after multiple publications reported that the Jennifer’s Body star and MGK had called it quits just weeks after announcing that they’re expecting their first baby together, with several reporting that the breakup had happened in November. Reps for both parties did not respond when Billboard reached out for comment at the time.

Fox and the rapper-turned-rocker had been in an on-and-off relationship since 2020, getting engaged in 2022, the same year she finalized her divorce from the actor. The following year, the pair called it quits before getting back together later in 2023.

Prior to her relationship with MGK, the Pretty Boys Are Poisonous author welcomed three children — 12-year-old Noah, 10-year-old Bodhi and 8-year-old Journey — with Green. The “Bad Things” singer is also a dad to daughter Casie, whom he shares with ex Emma Cannon.

While speaking to TMZ, Green added, “I just want the best for [Megan], I want the best for the baby, I want the best for our kids.”

“That’s a shame,” he continued. “I’m heartbroken about it. I know she’s been so excited, and the kids are so excited, for life and the change … I don’t know the facts of it, but if that’s the case, that’s a tragic situation.”
