Megan Fox's Ex-Husband Brian Austin Green Slams Machine Gun Kelly Amid Cheating Rumors: 'Grow Up'

Megan Fox's ex-husband, Brian Austin Green, has fired shots at Machine Gun Kelly, telling the rapper to "grow up" over an alleged text messaging scandal.

Fox and MGK were reportedly on a Thanksgiving trip to Vail, Colorado, when she decided to go through his phone, suspecting he was texting other women "behind her back."

Amid their breakup, Megan Fox has purchased an $8 million mansion in L.A., as sources claim their split is final.

Fox's ex-husband, Brian Austin Green, has reacted to news of the actress' relationship troubles, telling Machine Gun Kelly to "grow up" due to reports of him allegedly cheating.

Fox and MGK had planned to visit Colorado over Thanksgiving weekend but had to cut short their trip after she "found material on MGK's phone that was upsetting."

The situation seemingly irritated her ex-husband, who questioned why the "Hotel Diablo" rapper would act that way amid her pregnancy.

"I didn't even know," Green told TMZ on Thursday when he was asked about their breakup. He then let out a sigh when he was told about the situation that brought about their breakup.

"How old is he? … He's in his 30s, isn't he? … But in your 30s, like, f-ck. Grow up. Like, she's pregnant," he said.

Green went further to note that he "wants the best" for the "Jennifer's Body" actress amid her pregnancy.

"I just want the best for her," he said. "I want the best for the baby. I want the best for our kids. That's a shame."

Green then shared his disappointment about MGK's alleged infidelity.

"I'm heartbroken about it because I know she's been so excited," he told the news outlet. "And the kids are so excited for life and the change and all of that."

Although he revealed that he doesn't know "the facts" about their split, he stated that the situation is "tragic."

Green and Fox were married between 2010 and 2021 and share three sons: Noah, Bodhi, and Journey.

Fox was allegedly left feeling "distraught" and "blindsided" by MGK's alleged infidelity but is now relying on Green's fiancé Sharna Burgess for support.

According to the Daily Mail, an insider shared that Burgess is helping her navigate the "painful" split from the rapper and cares "deeply" about the "Transformers" actress.

"Brian and Sharna know what Megan has been through and is going through, and they both care about her deeply," a source told the news outlet. "She is the mother of Brian's kids, who are also Sharna's soon-to-be stepchildren."

"Sharna knows how difficult being pregnant can be and has been lending her support to Megan," the source continued. "She genuinely cares and feels for her. Breakups alone are so painful,l but breaking up while pregnant is even more so."

They added, "She only wants her to be okay and has offered to help her in any way she can. This means a lot to Megan. The women in her life are really stepping up to the plate and she appreciates this more than they know."

Fox recently bought an $8 million mansion in L.A. but doesn't plan to stay with her ex-fiancé, MGK.

According to TMZ, sources say the exes had not been living together over the past year, as the actress had been renting her home since then.

Although MGK bought a home years ago, it is said that Fox was concerned about the safety of staying there and chose to live on her own because he always had guests over.

She is now ready to settle down in one place and will soon move into her newly purchased home. MGK is not expected to move in with her after Fox called it quits on their relationship.

Fox reportedly bought her new home before they broke up, but sources say they'd never planned to stay together as they'd "never been a good match living together."

Fox and Kelly's breakup may be complicated as it comes a month after they announced that they were expecting their first child together.

Not even welcoming a baby can change her mind from splitting from Kelly, as sources told the Daily Mail that she's grown tired of his behavior and is now turning her attention to raising her unborn child.

"Megan was just done with all of it," one source told the news outlet. "She was done with his behavior and the way that he treated her."

"When she fell pregnant, he thought it meant that she would stay with him no matter what - and it is not the case," the source added. "The most important thing in Megan's world right now is her unborn baby, and she has no problem raising the child on her own."

Fox is also the mother of sons Noah, Bodhi, and Journey, whom she shares with ex-husband Brian Austin Green. Kelly has a daughter, Casie, with ex-wife Emma Cannon.
