Megan Fox Broke Up With Machine Gun Kelly over Content On his Phone

Machine Gun Kelly and Megan Fox have split over four years together.

According to TMZ, Fox saw something on MGK's phone that was so upsetting that she ended a Thanksgiving vacation with him and ended their relationship.

To complicate matters, Megan is pregnant with MGK's baby, due in March.

A source who spoke to People believes the pair will get back together.

 "Their relationship has always been bumpy. They love each other but don't have compatible personalities. They're both hot-heads, dramatic and stubborn. When they're good together, they're great."

"They will very likely get back together," adds the source. "They've split in the past and then worked things out.

What do you think Fox saw on that fun?  Just the typical infidelity signs, or something weird and freaky for the blood-drinking rapper-turned-rocker who used to be signed to The Diddler?
