Brian Austin Green has taken aim at the musician by sharing a fiery direct message he received from Megan Fox’s current (and possibly ex) partner amid the actress’ ongoing pregnancy and rumored split.

“Stop asking when our child is gonna be born. you the FEDS [rat emoji] [cop emoji],” MGK wrote in a scathing message to Green, accusing the former “Beverly Hills, 90210” star of feeding information to the press. “Quit calling TMZ and focus on that apology you owe me for speaking my name in public.”

MGK didn’t stop there. In the final line of the message, he took a jab at Green’s long-running career.

“You chose the wrong one to f-ck with mr child actor. go back to cereal commercials.”

Green, who started his acting career in childhood, didn’t appear fazed by the jab.

He posted a screenshot of the DM to social media, adding his own caption. “Didn’t know ‘child actor’ was something bad,” he wrote, before sarcastically warning, “Leo, careful. He may be coming for you next [laughing face emoji x4],” seemingly referring to Leonardo DiCaprio.

Green and Fox, who were married from 2010 to 2022, share three children: Noah, 12, Bodhi, 11, and Journey, 8. Since their divorce, Green has remained vocal about issues surrounding his ex-wife’s high-profile relationship with the 34-year-old rocker. Meanwhile, MGK is also a father to 15-year-old daughter Casie, whom he shares with ex Emma Cannon.

Last month, Green took another shot at MGK after the rapper implied in an Instagram post that he had a line of communication with Fox, something Green claimed wasn’t true. “Bro. Just be honest for once in your life,” Green wrote in a pointed Instagram Stories. “Stop caring so much about how you’re perceived that you will try and drag other people.”

The situation has only intensified since Fox announced in November 2024 that she was expecting her first child with MGK. By December, reports surfaced that the couple had broken up, just weeks after her pregnancy reveal.

Sources told Page Six that Fox discovered MGK was communicating with other women behind her back after checking his phone during a Thanksgiving trip.

“When they went away for the Thanksgiving holiday, she became suspicious and decided to go through his phone,” one insider revealed. “She found text messages involving other women and decided she was done.”

As Fox prepares for the arrival of her baby, reportedly due this month, she’s leaning on her sister, Kristi Fox, for support.

“Megan is leaning on her sister Kristi amid her split from Colson,” the source told the outlet. “She’s due any day now.”

An insider also told Page Six that the “Bloody Valentine” singer “fully intends” to be an active and present father in the child’s life, even after his recent breakup with the actress.

“He and Megan have still been in communication,” the source shared. “He loves Megan and wants nothing more than to be a family unit.”

The exposed DMs come after MGK was recently spotted in Los Angeles looking drastically different from the bleach-blond, clean-shaven rocker fans had grown accustomed to. In his latest appearance, the artist sported long, tousled hair, a rugged beard, and a grungy boho-inspired look that had fans doing a double take.

Despite the altered aesthetic, there was no mistaking him thanks to his signature tattoos, the distinctive ink sprawling across his neck and chest made it clear this was, in fact, Colson Baker.

Spotted leaving a trendy LA café solo, the artist didn’t speak to reporters, but his new look did plenty of talking on its own. The muted tones, layered textures, and effortless rockstar energy signal what could be the start of MGK’s post-Megan metamorphosis.

Neither Fox nor MGK has publicly commented on the leaked DM or the current state of their relationship. But if the ongoing feud with Green is any indication, things behind the scenes are anything but calm.
