“Stop calling TMZ and focus on that apology you owe me for speaking my name in public,” Kelly wrote in an Instagram DM

Brian Austin Green is hitting back after Machine Gun Kelly slid into his DMs.

The actor, 51, reshared a screenshot of his DMs with Machine Gun Kelly on his Instagram Stories after the singer, 34, messaged him to chastise Green for repeatedly asking when his baby with Megan Fox, 38, is due.

Kelly, born Colson Baker, is expecting his first baby with Fox and is already dad to daughter Casie, 15. Green shares his three kids — Noah Shannon, 12, Bodhi Ransom, 10 and Journey River, 8 — with the Jennifer’s Body alum.

“Stop asking when our child is gonna be born. you the FEDS 🐀👮‍♂️,” Kelly wrote to Green. “Quit calling TMZ and focus on that apology you owe me for speaking my name in public.”

Green wrote on Feb. 3 in a since-expired Instagram Stories post shared by TMZ: “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.”

The Knots Landing star told PEOPLE at the time he hadn’t heard from Kelly after the post, and said he wasn’t expecting to.

“That’s not something that I normally do, but it just really at the time, really got under my skin to read about his sort of take on it,” Green shared. “So I spoke my mind, but then I’ve since come to terms with the fact that I won’t do that anymore. I’m going to shut up and just sit back.”

“You chose the wrong one to f— with mr child actor. go back to cereal commercials,” he added.

The actor’s comments about Kelly came after he first reacted to news of the rapper’s split with Fox in December, only a few days after it was reported that the pair had called it quits.

“I didn’t even know. No. I had no idea,” Green said at the time when asked about the breakup in a clip shared by TMZ.

After the reporter alleged that Kelly was unfaithful to his former fiancée, Green responded, “How old is he? Do you know? He’s in his 30s. Nice … In your 30s, like — I don’t know. Grow up. She’s pregnant.”

“I just want the best for her, I want the best for the baby, I want the best for our kids,” Green insisted.

“That’s a shame. That’s a shame. I’m heartbroken about it because I know she’s been so excited and the kids are so excited for life and the change and all of that,” he added.

Underneath the photo on his Instagram Stories, Green wrote, “😂😂😂😂 I didn’t know ‘child actor’ was something bad.”

“Leo, careful,” Green continued, seemingly referencing Leonardo DiCaprio. “He may be coming for you next 🤣🤣🤣🤣.”
