AceShowbiz - The drama between Machine Gun Kelly (MGK) and Brian Austin Green has escalated yet again. On Friday, April 4, MGK - whose real name is Colson Baker - debuted a new drink at his 27 Club Coffee lounge in Cleveland, Ohio. The green beverage, cheekily named "Child Actor Margarita," seemingly pokes fun at Green, the '90s teen idol turned actor.

The Instagram caption added fuel to the shady name, "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," alluding to Green's iconic role in "Beverly Hills, 90210" and making it clear that the drink's name was no coincidence.

This latest move by MGK comes in the aftermath of a heated back-and-forth earlier in the month. It was revealed that MGK had sent Green a harsh direct message following an inquiry about Megan Fox's pregnancy.

The rapper's DM, which Green shared publicly, included lines like "Quit calling TMZ and focus on that apology you owe me for speaking my name in public." He added, "You chose the wrong one to f**k with mr child actor. go back to cereal commercials."

Green, taking the dig in stride, responded with humor, stating on his stories, "I didn't know 'child actor' was something bad."

Green's fiancee, Sharna Burgess, later defended her partner. In a now-deleted Instagram story, she addressed the feud, "lol That was about the equivalent of a dog pissing on its territory making it known it's back in the area."

Sharna denied leaking news to the media and shared insights into why they were asking about the baby, "Our kids are so excited about the arrival of their baby sibling and we are excited FOR them. They have been asking nearly every day of their 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."

Burgess, who shares a 2-year-old son named Zane with Green, while Green shares three children - Noah, Bodhi, and Journey - with Megan Fox who recently gave birth to MGK's second child.

As the feud continues to unfold, fans and followers are undoubtedly keeping a close eye on every social media update. Whether the drinks and DMs will give way to a truce, or fuel further drama, remains to be seen.
