Megan Fox Claps Back At Brian Austin Green's Diss On New Instagram Post

In today's edition of Petty Exes On The Internet, Brian Austin Green is (again) trying to take a jab at ex-wife Megan Fox in an Instagram caption that I can only describe as yikes.

However, Megan Fox is doubling down on the drama and clapping back at Brian, thus leaving fans with a juicy, soapy story I cannot wait to dive into with y'all.

As we all know by now, Megan Fox and Brian Austin Green called it quits last year.

The couple had been dating since 2005 before tying the knot in 2010. Megan and Brian have three children together: eight-year-old Noah, seven-year-old Bodhi, and four-year-old Journey.

In the weeks following their split, Megan began dating rapper Machine Gun Kelly.

The pair have been, for lack of a better phrase, absolutely obsessed with each other for nearly a year now.

While the pair have been making headlines since the beginning of their relationship, no one has been more vocal about it than Megan's ex.

Let's just say Brian Austin Green has had zero issue being super petty on social media.

Fans may recall Brian's pettiness last summer when he mocked Megan on Instagram.

After Megan posted a picture with Machine Gun Kelly with the caption "Achingly Beautiful Boy... My heart is yours," Brian turned around and posted pictures of their sons with the same caption.

Unfortunately, that wasn't the last time the two had social media drama.

On Halloween, Brian posted a picture of himself and their son, Journey, in costumes, writing "Hope you all had a good Halloween!"

Megan immediately responded to the now-deleted post.

"Why does Journey have to be in this picture? It's not hard to crop them out. Or choose photos that they aren't in," the 35-year-old wrote at the time.

"I had a great halloween with them yesterday, and yet notice how absent they are from my social media. I know you love your kids, but I don't know why you can't stop using them to posture via Instagram."

"You're so intoxicated with feeding the pervasive narrative that I'm an absent mother, and you are the perennial, eternally dedicated dad of the year. You have them half of the time," Megan continued in her scathing comment.

"Congratulations you truly are a remarkable human! Why do you need the internet to echo back to you what should be inexhaustibly evident in the way your children love you?" Megan's comment finished.

Brian did not respond to her comment, but did delete the picture and re-upload a version with Journey cropped out.

Yikes.

As for Brian Austin Green, he began dating *Dancing with the Stars* pro Sharna Burgess at the beginning of this year.

Seems like both pairs are unbothered and happy, right?

Well, one couple is, the other one has Brian Austin Green in it so, you know there's going to be some petty at play.

Posting a picture with Sharna on Tuesday, BAG wrote: "It’s been a really long time since I’ve been with someone I can truly share life with."

Naturally, fans took this remark as a diss to his ex-wife Megan, who he was with for 15 years.

"Ouch..." commented one follower.

"THE SHADE!" echoed another.

However, Megan wasn't down to play these games and left the perfect reply.

Under Sharna's comment, Megan wrote "Grateful for Sharna."

Allegedly, the comment has since been deleted — but not before the fans got ahold of it.

"She is thankful so he can stop being a grump," commented one fan.

"Ya, that wasn't being supportive... That was def her throwing shade," agreed another.

"She's the bigger person, tbh" said a different fan.

It's clear Brian is still interested in the petty Instagram games with Megan, but I think she handled it perfectly!
