Machine Gun Kelly’s coffee shop, 27 Club Coffee, has entered the chat amid his ongoing feud with Brian Austin Green.
The eatery, located in his home state of Ohio, unveiled a new cocktail on Friday, April 4, that is seemingly directed at Green’s early career: the “Child Actor Margarita.”
“We put a childish twist on this margarita meant for those days when you just don’t wanna act like an adult. 9021-OMG 
#27ClubCoffee,” the restaurant teased via Instagram, adding a cheeky jab at Green’s time as David Silver on Beverly Hills, 90210 with the “9021-OMG” quip.
The bright green drink is described as “Sour. Soft. Basic.” on the 27 Club Coffee menu. It is made up of tequila, lime, agave, orange and green glitter.
Pregnant Megan Fox and MGK ‘Never Fully Lived Together,’ Her New House Info
The release of the Child Actor Margarita is the latest barb between Kelly, 34, and Green, 51, who have been publicly beefing since late 2024.
The feud began shortly after the “Bloody Valentine” singer (real name Colson Baker) and Megan Fox broke up in November 2024, ending a two-year engagement. The split made headlines shortly after Fox, 38, announced she was pregnant with her and Kelly’s first baby, her fourth.
Fox shares three sons, Noah, 12, Bodhi, 11, and Journey, 8, with Green. The exes were married more than 10 years before calling it quits in May 2020. Fox moved on with Kelly that same year, and they welcomed a daughter last month. (Kelly also shares daughter Casie, 15, with Emma Cannon.)
Prior to the baby girl’s arrival, Green slammed Kelly for allegedly not being grown up enough to support Fox amid her pregnancy.
“He’s in his 30s, right?” Green asked a TMZ reporter in December 2024, referring to Kelly. “But in your 30s, I don’t know, grow up. Like, you know, she’s pregnant.”
The former BH90210 actor explained, “I just want the best for her. I want the best for the baby. I want the best for our kids.” (Green is also the father of Kassius, 23, whom he shares with ex Vanessa Marcil. He and fiancée Sharna Burgess welcomed son Zane in June 2022.)
Brian Austin Green Slams MGK Amid Megan Fox Pregnancy: ‘Just Be Honest’
In February, Green asked Kelly to “be honest for once in your life” via his Instagram Story after seeing a story about Kelly calling out an article written about his relationship with Fox.
The following month, Green posted direct messages he allegedly received from Kelly to his own social media feed. “Stop asking when our child is gonna born. You the FEDS,” one message allegedly from the rapper read. “Quit calling TMZ and focus on that apology you owe me for speaking on my name in public.”

Kelly’s alleged rant included a jab at Green’s career. “You chose the wrong one to f*** with mr child actor. Go back to cereal commercials,” the musician’s reported message read.
Green quipped, “I didn’t know ‘child actor’ was something bad. Leo [DiCaprio], careful. He may be coming for you next.”
As Green and Kelly publicly exchanged jabs, Fox has remained neutral as she recently gave birth to her and Kelly’s baby girl. However, a source exclusively told Us Weekly in March that the actress “does not love that MGK is fighting with Brian.”
The insider added, “Megan wants to stay out of their fighting. She feels it’s their issue, not hers.”
