Brian Austin Green says Machine Gun Kelly's comments 'got under my skin'

Brian Austin Green had previously shared a now-expired Instagram Story criticizing Machine Gun Kelly for what he perceived as an attempt to involve others in his personal matters.

However, he now says he has come to terms with not speaking out again.

While speaking to People on Wednesday, February 5, Green, 51, reflected on his decision to post about Kelly, 34, where he reacted to an article about his relationship with Fox, 38.

Green reposted an image describing how MGK, 34, had “call[ed] out” TMZ’s narrative that he and Fox, 38, are “not on good terms” ahead of welcoming their first baby together.

"That's not something that I normally do, but it just really at the time, really got under my skin to read about his sort of take on it," Green said on Wednesday, February 5.

Green had originally posted on February 3, writing, "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," reported Page Six.

He now says he has made peace with the situation and has no plans to speak on it further.

"So I spoke my mind, but then I've since come to terms with the fact that I won't do that anymore. I'm going to shut up and just sit back," Green added.
