Brian Austin Green Had a Hilariously Petty Response to Megan Fox’s Instagram Post About Machine Gun Kelly

Brian Austin Green has an “achingly beautiful” message for estranged wife Megan Fox and her new beau, Machine Gun Kelly. Recently, the Transformer actor went Instagram official with the rapper, who she gushed about in the caption of the photo. But instead of Green giving his ex’s post a double-tap like everyone else, he savagely clapped back at Fox with a post of his own.

Brian Austin Green hilariously mocked Megan Fox’s post

On Aug. 5, Fox publicly declared her love for Machine Gun Kelly, whose real name is Colson Baker, on Instagram — and her ex-husband savagely mocked her for it.

The actor shared a black and white mirror selfie of herself and the rapper wrapped in towels along with the caption, “Achingly Beautiful Boy… My heart is yours.”

Hours after Fox posted the sweet photo to her feed, Green used her same caption to gush over their three children, Noah Shannon, 7, Bodhi Ransom, 6, and Journey River, 3, as well as his son Kassius, 18, who he shares with ex Vanessa Marcil.

Though he didn’t mention Fox in the caption, it was clear to fans who Green was directing his post at. Shortly after the Beverly Hills, 90201 alum shared the series of photos of his sons, many took to the comments to applaud him for delivering the “best clap back.”

But while some praised the actor for winning over the Internet with his epic “burn”, a majority of fans complimented him for showing off his love for his sons, who many agreed are indeed “achingly beautiful boys.”

The pair were married for nearly a decade but decided to call it quits late last year after Fox returned home from filming Midnight in the Switchgrass overseas and told him about her budding romance with Kelly.

“Megan has continued working and she met this guy Colson on set on this film she’s working on,” Green shared during an episode of his podcast …With Brian Austin Green. “I’ve never met him. He goes by Machine Gun Kelly. I’ve never met him, but Megan and I have talked about him and they’re friends at this point. And from what she’s expressed, he’s just a really nice, genuine guy. And I trust her judgment. She’s always had really good judgment.”

The pair officially announced their divorce in May 2020.

That same month, Fox began sparking romance rumors with Kelly. She even appeared in the music video for his song, “My Bloody Valentine,” which convinced fans that they were an official couple.

However, it wasn’t until Kelly tweeted, “life imitated art on that one,” along with the lyrics, “I’m calling you my girlfriend, what the f*ck,” that fans seemingly got confirmation that he and Fox were officially a couple.

Since then, Fox and Kelly haven’t been afraid to showcase their budding romance in the public eye.

And while some might think Green feels some type way about his ex-wife moving on so quickly with someone else, it turns out that he has no hard feeling toward Fox whatsoever.

In fact, he recently revealed that he supports Fox’s relationship with Kelly as he wants nothing but the best for her.

“I wish Megan the absolute best in everything. I want her to be completely happy for her and for the kids,” he said during a recent appearance on Hollywood Raw podcast. “That’s super important. Nobody wants to be around somebody that’s unhappy. Nothing good comes out of that. That’s a terrible situation.
