According to TMZ, the split happened over Thanksgiving after Megan allegedly found something "upsetting" on MGK's phone. "[She was] blind-sided," a source told People of the breakup. "She's been distraught."
But the insider also said Megan was "trying to focus on" her baby, who will be her fourth child behind sons, Noah, 12, Bodhi, 10, and Journey, 8, whom she shares with her ex-husband Brian Austin Green. This will also be MGK's second child after his daughter, Cassie, 15.
