Brian Austin Green is putting MGK (formerly Machine Gun Kelly) on blast.
The Night They Came Home actor took to his Instagram Stories this week, where he shared a screenshot of a DM with the “Bloody Valentine” singer, according to People. “Stop asking when our child is gonna be born. you the FEDS 
,” Kelly wrote to Green in the DM, referring to his upcoming baby with Megan Fox. “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,” he added. In response, Green wrote over the message, “
I didn’t know ‘child actor’ was something bad.”
“Leo, careful,” he added, in reference to Leonardo DiCaprio, another child actor. “He may be coming for you next 
.”
Green, who shares sons Noah, Bodhi and Journey with ex-wife Fox has a history of sharing his opinion about MGK. “Bro. Just be honest for once in your life. Stop caring so much about how you’re perceived that you will try and drag other people,” Green reportedly wrote in February in a since-expired Story in reaction to a headline that said MGK was trying to downplay reports that things were not good between him and Fox.
MGK and the Jennifer’s Body actress began dating in 2020 after meeting on the set of Midnight in the Switchgrass, and the couple got engaged in early 2022. In November 2024, Fox announced that she was pregnant, sharing a photo of her baby bump as well as a picture of her positive pregnancy test on Instagram and writing, “nothing is ever really lost. welcome back 
.” She also tagged MGK in the post. By December, the couple had reportedly broken up.
Green had previously counseled Kelly to “grow up, she’s pregnant” after news broke that he and Fox had split a month after announcing their baby news.
