Megan Fox dumped Machine Gun Kelly after she ‘found text messages’ from other women in his phone

Megan Fox is “done” with Machine Gun Kelly after discovering he was talking to other women behind her back, a source exclusively tells Page Six.

“When they went away for the Thanksgiving holiday, she became suspicious and decided to go through his phone,” our insider says.

The “Transformers” star, 38, “found text messages involving other women and decided she was done” with MGK, whose real name is Colson Baker.

The “Jennifer’s Body” actress always “had trust issues” with the rapper and singer-songwriter, 34, “because of past behavior.” They’ve also had their ups and downs over the past few years, but she was willing to look past all that, our insider says.

Megan wanted to “rebuild her trust with Colson and was excited to grow their family together,” our source explains.

However, after discovering the text messages, she’s changed her tune.

“Megan is a strong, independent woman and doesn’t need a man in her life,” our insider explains.

Reps for Fox and MGK did not immediately respond to Page Six’s requests for comment.

As we previously reported, the on-again, off-again couple — who are expecting their first child together — broke up over Thanksgiving weekend while in Vail, Colo.

The pair’s split happened just two weeks after the “Midnight in the Switchgrass” actress announced she was expecting her fourth child, and her first with MGK.

On Nov. 11, Fox shared a photo of her cradling her bump while covered in oil. She also posted a snapshot of a positive pregnancy test.

“nothing is ever really lost. welcome back 👼🏼❤️,” she captioned the carousel of images while also tagging the “Bloody Valentine” rocker.

The actress is already a mother to her and ex-husband Brian Austin Green’s children: Noah, 11, Bodhi, 9, and Journey, 7.

MGK welcomed daughter Casie, now 15, in 2009 with then-girlfriend Emma Cannon.
