Brian Austin Green and Machine Gun Kelly have become embroiled in a dispute on social media. The two have been feuding online for some time, with Green calling out Kelly on Thursday for his suggestive use of aggressive language. He said:

"Leo, careful. He may be coming for you next 🤣🤣🤣🤣."

More about the dispute between Brian Austin Green and Machine Gun Kelly

Last month, Brian Austin Green first called out the "Rapper Devil" singer on his Instagram Story.

The Knots Landing actor said:

"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."

In an exclusive interview with People Magazine that same month, he further explained the reason why he did so:

"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. 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."

The source of their dispute seemingly began when Kelly had texted the "Beverly Hills, 90210" actor, asking him to not intervene or be inquisitive about the birth of his and Megan Fox's child.

Machine Gun Kelly wrote:

"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**k with mr child actor. go back to cereal commercials."

Megan Fox and Brian Austin Green share three children: Noah, Journey, and Bodhi. Machine Gun Kelly, on the other hand, has a daughter from a previous relationship. Green also shares a son, Zane, with his fiancé, Sharna Burgess.

On Thursday, Burgess posted an Instagram story emphasizing that "A successful co-parenting relationship starts with communication and respect."

She further added:

"When kids are in a split household the greatest thing we can do is make them love and feel safe in both homes, like both homes are also friends and share love and communication.We work to always keep our language and experiences positive, and when talking about their other home we always talk about it with love and support,"

She also added:

"Our kids are so excited about the arrival of their baby sister and we are excited FOR them. They have been asking us nearly every day of her arrival for about a month now. Naturally when they ask us to find out how mama is doing, we say no problem and do just that."

This was a subtle yet obvious dig at Kelly, who recently welcomed his first child with the Jennifer's Body actress on Thursday.

Back in December 2024, in a video released by TMZ, Brian Austin Green had reacted to Machine Gun Kelly and Megan Fox's split amid her pregnancy and rumors of Kelly having allegedly cheated on Fox during their relationship, saying:

"I didn't even know. No. I had no idea. 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,"

He further added:

"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,"

Megan Fox and Brian Austin Green were married between 2010 and 2020. According to People Magazine, Megan filed for divorce in November 2020.
