Megan Fox's ex, Brian Austin Green, is calling out Machine Gun Kelly for the threatening DM he sent him on Thursday.

Green took to Instagram to upload a screenshot of MGK's message, which asked the Beverly Hills, 90210 alum to stop asking about the due date of his and Fox's child. He also referred to him as "mr child actor," suggesting that he "go back to cereal commercials."

Green, however, slammed the musician, noting that he didn't know being a child actor was a bad thing. He also seemingly referred to Leonardo DiCaprio, another former child star, suggesting that he be "careful" as MGK may "come for him next."

Fans have since begun reacting to the news, and while some are siding with MGK, others are slamming him for threatening Brian Austin Green. Here's what one fan said, for instance:

"Mgk is right, he should mind his business."

Others, however, are defending Brian Austin Green, noting that he, too, shares kids with Megan Fox, which means her child with MGK would be their sibling. Here's what fans are saying on X:

"Why does he care when their child is born," someone probed.
"MGK definitely crossed a line with that message. The tension is real between them," another pointed out.
"I don't get it tho mgk did have the right to be mad because who tf asks about another couple's due when it is none of their business?? am I missing something here???" one user noted.

Even more are reacting to the screenshot with varied opinions:

"Brian Austin Green hit him with the ‘know your place’ energy," someone quipped.
"Why is that man concerned about when another man’s child is born," one more echoed.
"Why He cares? Because his kids are gonna have a new sibling! That's why... they are still family, still co-parenting..." yet another chimed in.

In the screenshot, Machine Gun Kelly sent the following text to Brian Austin Green:

“Stop asking when our child is gonna be born. you the FEDS 🐀👮‍♂️. Quit calling TMZ and focus on that apology you owe me for speaking my name in public. You chose the wrong one to f— with mr child actor. go back to cereal commercials”

Green, however, penned over the screenshot:

“😂😂😂😂 I didn’t know ‘child actor’ was something bad. “Leo, careful. He may be coming for you next 🤣🤣🤣🤣.”

Megan Fox and Machine Gun Kelly welcomed their first child, a girl, just this week. The pair announced the news in a post on Instagram just today, as the latter uploaded a video of himself holding the newborn's hands. The caption read:

"She’s finally here!! Our little celestial seed 3/27/25."

At the time of writing, the couple has yet to disclose their newborn's name.
