MGK Keeps Feud Brewing With Brian Austin Green In Petty Cocktail Jab

Machine Gun Kelly isn’t done throwing shade at Brian Austin Green, and this time, he’s serving it chilled with a salted rim.

The rapper-turned-rocker, whose real name is Colson Baker, appeared to take a fresh dig at Megan Fox’s ex-husband, Brian Austin Green, on Friday with a cheeky new addition to his 27 Club Coffee menu in Cleveland, Ohio.

“NEW DRINK ALERT: CHILD ACTOR MARGARITA,” the lounge teased on Instagram, posting a vibrant green cocktail as part of their latest offering.

“We put a childish twist on this margarita meant for those days when you just don’t wanna act like an adult. 9021-OMG [sly face emoji] #27ClubCoffee,” the caption continued, in what many are reading as a not-so-subtle reference to Green’s days as a star on the iconic teen soap "Beverly Hills, 90210."

While Green’s name was never explicitly mentioned, the all-green drink, combined with the pointed nod to his breakout show, makes it hard to see the post as anything but a low-key diss.

This latest jab follows a now-viral DM that Green exposed last month, an unfiltered message from the “Emo Girl” musician sent during a private conversation regarding Megan Fox’s pregnancy.

“Stop asking when our child is gonna be born. you the FEDS [rat emoji] [police officer emoji],” MGK wrote in the message that Green later made public.

“Quit calling TMZ and focus on that apology you owe me for speaking my name in public,” the message continued. “You chose the wrong one to f-ck with mr child actor. go back to cereal commercials.”

Green, who seemingly brushed off the exchange with humor, responded on Instagram Stories: “didn’t know ‘child actor’ was something bad.” He then added, “Leo, careful,” appearing to joke about Leonardo DiCaprio’s own start in the industry. “He may be coming for you next [four laughing face emojis].”

The drama didn’t stop there. Green’s fiancée, former "Dancing with the Stars" pro Sharna Burgess, weighed in with her own commentary, though she later deleted the post.

“lol That was about the equivalent of a dog pi--ing on its territory making it known it’s back in the area,” she wrote, referring to MGK’s message.

Burgess emphasized the importance of unity in co-parenting, continuing, “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 added.

“Our kids are so excited about the arrival of their baby sister and we are excited FOR them,” Burgess continued. “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.”

Green and Burgess share a 2-year-old son, Zane, while the actor also co-parents sons Noah, 12, Bodhi, 11, and Journey, 8, with Fox.

Megan Fox and Machine Gun Kelly may have gone their separate ways romantically, but when it comes to their new baby girl, the former couple is standing united.

The "Jennifer’s Body" star and the "my ex's best friend" artist got engaged in January 2022 and were one of Hollywood’s most talked-about pairs. But in December 2024, just weeks after announcing they were expecting a child together, the two quietly called it quits.

Despite the end of their engagement, a source previously told PEOPLE Magazine that Fox and Kelly “are on the same page when it comes to co-parenting.”

“Whatever issues they have, Megan and MGK both are on the same page when it comes to co-parenting,” the insider shared. “Right now they’re amicable.”

The former couple, who had previously made headlines for their intense connection and PDA-filled red carpet appearances, are now shifting their focus entirely to their growing family.
