Brian Austin Green responded to his ex-wife Megan Fox after she shared a photo with her boyfriend Machine Gun Kelly on social media.

On Wednesday, the "Transformers" star took to Instagram and posted a photo of her with her new love. It appeared that the two just finished swimming because Fox was wearing a bikini and both had a towel wrapped around their waist.

"Achingly Beautiful Boy... My heart is yours," Fox wrote in the caption.

Just hours after Fox's post, Green also shared snaps of his four children, three of whom he shares with Fox.

"Achingly beautiful boys...... My heart is yours," he wrote in the caption.

Green's post received mixed reactions from his followers. Some called his move "savage" another said it was the "best clap back" to his ex.

"Ahhh I see what u did there ... I achingly like it," one commented.

"Savage love it, you’re an awesome dad," another added.

"That’s it... you win the Internet today," another netizen wrote.

"Yes! Much better than her post," @jennifer_rye80 commented.

Meanwhile, some slammed Green for taking a dig at his ex-wife.

"Now we know why she broke up with you. Your children must be more mature than you. Move on," @caroldiasdc commented.

"So unnecessary to bring the kids into it. You were handling the situation like a man now not so much. two wrongs don’t make a right," @ashleystew913 wrote.

"Aren't you are 47-year-old grown man?" another asked.

Meanwhile, Green said in a recent interview that he wants Fox to be happy. He also wished her the “absolute best.”

“I wish Megan the absolute best in everything. I want her to be completely happy, for her, for the kids. That’s super important," he said.

"No one wants to be around somebody that’s unhappy, nothing good comes out of that. That’s a terrible situation.”

Green also said that he learned about Fox and Kelly’s relationship in his own way and not from the press. Fox and Kelly made their relationship Instagram official when they shared a photo of them together on the platform last week.
