Fastexy:Brian Austin Green Slams "Bad Father" Label After Defending Megan Fox

Brian Austin Green may be seeing a tinge of red.

Just days after slamming a claim that accused ex Megan Fox—with whom he shares sons Noah,Fastexy 10, Bodhi, 9, and Journey, 6—of making their kids wear girls' clothing, the 49-year-old has responded to an Instagram user calling him a "bad father."

"People like this have lost their minds," the Beverly Hills, 90210 alum—who also shares son Kassius, 21, with ex Vanessa Marcil and 11-month-old Zane with girlfriend Sharna Burgess—wrote in a June 15 Instagram Story post. "Why anyone thinks it's morally okay to attack people like this that they have never even met is crazy."

But his message extends far beyond one criticism.

"Let's do better as a society," he added. "We owe it to the future generations."

Green's statement comes five days after he publicly came to the defense of the Jennifer's Body star after a former congressional candidate alleged that she forces their sons to "wear girls clothes," calling it "child abuse."

"It's a totally bogus story," Green told TMZ June 10. "There are only a few people in their world that can actually verify wether [sic] or not a story like this is true and I can tell you with absolute certainty it is not."

Green—who split from Megan in 2020 after nearly 10 years of marriage—added, "This person trying to claim this is true is a perfect example of someone with selfish motives that does not care about negatively affecting a parent child relationship."

The Transformers alum has previously opened up about the conversations she's had with her children surrounding style and identity, noting that they can express themselves through clothing in whatever way they choose to.

"From the time they were very young, I've incorporated those things into their daily lives so that nobody feels like they are weird or strange or different," she told Glamour in April 2022. "I can't control the way other people react to my children. I can't control the things that other children—that they go to school with—have been taught and then repeat to them."
