Back in May, Brian Austin Green confirmed to PEOPLE that he and Megan Fox had separated after 10 years of marriage. Though admittedly blindsided, he said they agreed to part on amicable terms for the sake of their three sons — Journey, 3, Bodhi, 6, and Noah, 7 — but that all went out the window when he mocked his ex's latest social media post.

Since their split, Fox began a relationship with rapper Machine Gun Kelly and posted her first picture with him on Instagram Wednesday (August 5). "Achingly Beautiful Boy... My heart is yours 🔪♥️🔪" she captioned the mirror selfie with her new beau.

Well, her estranged husband apparently was not impressed with her ode to MGK, because a few hours later he posted a photo gallery of their kids (and his 18-year-old son Kassius, whom he shares with ex Vanessa Marcil) with the caption "Achingly beautiful boys...... My heart is yours."

Shots. Fired.

Kelly and Fox connected while shooting a new film, Midnight in the Switchgrass, in Puerto Rico before the coronavirus pandemic hit.

Green revealed that the Transformers star called it quits with him upon her return from filming. "She said, 'I realized when I was out of the country working alone that I feel more like myself and I liked myself better during that experience and I think that might be something worth trying for me,'" he told PEOPLE. "I was shocked and I was upset about it but I can’t be upset at her because she didn’t ask to feel that way. It wasn’t a choice she made, that’s the way she honestly felt. We talked about it a little more and said let’s separate for a bit… and so we did."

“We’ve had an amazing relationship and I will always love her and I know she’ll always love me," he added.
