AceShowbiz - Megan Fox allegedly will never reconcile with Machine Gun Kelly following their shocking split. It has been reported that the "Transformers" actress' breakup from the "Concert for Aliens" artist is "final" as she was "done with his behavior."

On Tuesday, December 10, a source spilled some details about the 38-year-old actress' split from the 34-year-old singer/rapper, whose real name is Richard Colson Baker. Speaking to Daily Mail, the source said, "Megan was just done with all of it. She was done with his behavior and the way that he treated her."

The source explained, "When she fell pregnant, he thought it meant that she would stay with him no matter what - and it is not the case. 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."

"She's left him before, but this time seems final," the insider went on to share. "Her friends support her wholeheartedly and over the past few years they have grown to really dislike him. Her friends were worried this was going to happen."

Another informant told the media outlet that Megan can no longer deal with their "high-school relationship" and "never-ending" drama. The informant elaborated, "The way they operate is drama. It's like a never-ending high school relationship. For weeks and months, everything was fine but when they get into fights, it is all or nothing."

"It took a turn for the worst during Thanksgiving," the informant continued. "She is convinced Colson is cheating on her, or has cheated on her. She has accused him of texting a bunch of girls and if it hasn't led to physical cheating, it is emotional cheating in her eyes. Now, Colson is trying to get back on track with her."

The revelation came shortly after it was said that Megan dumped MGK when they were on a trip to Vail, Colorado during Thanksgiving weekend. The two, who announced that they are expecting their first child together in early November, split after she allegedly found "upsetting material" on his phone. It led her to ask him to leave the vacation early, and they have not seen each other since.
