Megan Fox Responds To Estranged Husband Brian Austin Green's Public Diss Amid Mom-Shaming Allegations

The loved-up shot wasn't what caught Fox's attention. It was the Beverly Hills, 90210 actor's caption that caused his soon-to-be ex-wife to react.

Green and Sharna whisked his three children -- sons Journey, 4, Bodhi, 7, and Noah, 8 -- with Fox on a recent getaway to Florida.

Tagging the group at Walt Disney World Animal Kingdom, Green shared a video on Tuesday showing his kids having fun with Sharna.

He also posted a selfie, capturing him getting fresh with the former Dancing With The Stars pro.

Green then went on to fire shots at his ex.

Several fans immediately dropped comments, acknowledging the jab taken at Fox.

Green was married to the Transformers actress for 10 years before she filed for divorce in November.

Instead of ignoring the post or lashing out, Fox took the high road.

Making her presence known by dropping a comment, the actress replied, "Grateful for Sharna." She even added a purple heart emoji.

Sharna commented back, showing Fox love by sending two white heart emojis right back at her. As for Green, he's kept quiet.

The star -- who, for the most part, keeps her private life off of Instagram -- slammed her soon-to-be ex-husband months ago when he shared a photo with one of their sons on Halloween.

"Why does Journey have to be in this picture?" she commented on the post. "It's not hard to crop them out. Or choose photos that they aren't in. I had a great Halloween with them yesterday, and yet notice how absent they are from my social media."

She ended her rant with one last dig.

"Congratulations, you truly are a remarkable human," she wrote. "Why do you need the internet to echo back to you what should be inexhaustibly evident in the way your children love you?"
