Brian Austin Green and Machine Gun Kelly's drama continues. The '90210' actor shared the message the rapper sent to him on Instagram, and it seems like he is asking for a public apology after he commented on MGK's relationship with Megan Fox ahead of the birth of her first child with the musician.

In the messages, MGK calls him out for repeatedly asking about the arrival of Megan Fox’s baby. In a post shared on Instagram Stories, Green showed the singer’s message in which he chastised him for asking about Fox’s pregnancy and demanded an apology.

MGK, who is expecting his first child with the actress amid reports of struggles in their relationship responded to Green with a blunt message: "Stop asking when our child is gonna be born. you the FEDS," he wrote, before further telling Green to "Quit calling TMZ and focus on that apology you owe me for speaking my name in public."

Go back to cereal commercials."Green shared the screenshot of the DM on his Instagram, accompanied by his own sarcastic response. "I didn't know 'child actor' was something bad," he wrote.

Green added laughing emojis and made a playful reference to fellow actor Leonardo DiCaprio, saying, "Leo, careful... he may be coming for you next."

This isn’t the first time the pair have publicly exchanged words. Back in February, Green opened up to People about a previous Instagram post where he called out MGK’s take on an article discussing Green’s past relationship with Fox.

Green expressed frustration at the time, “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.” However, Green admitted the situation "really got under my skin" and later clarified that he wasn't planning to engage further in public drama.

I’m going to shut up and just sit back," he said. The actor later commented on reports about the split, stating that he didn’t have prior knowledge of the situation and expressed his concern for Fox and their children.

"I just want the best for her, I want the best for the baby, I want the best for our kids." He also criticized MGK’s behavior, remarking, “In your 30s... like — I don’t know. Grow up. She’s pregnant.”
