Megan FoxandMachine Gun Kellyare “still not in a good place,” a source tells PEOPLE, after the actress returned to Instagram Sunday to shut down rumors about the couple.

Fox, 36, who completely deactivated her Instagram account last week afterhinting at a potential breakupbetween her and 32-year-old Kelly (real name Colson Baker), shared a post after reactivating it stating that there wasno cheating involved in the relationship.

“There has been no third party interference in this relationship of any kind,” Fox wrote. “You need to let this story die and leave all of these innocent people alone now.”

A source who is familiar with both Fox and Kelly tells PEOPLE that theTransformersactress had initially suspected something was amiss and reacted out of emotion.

“She’s now posted that there was no cheating, but she initially thought there was and now is backtracking a bit,” the source says. “She was definitely hinting at infidelity with her first post. She regrets making it all so public, but was really upset in the moment.”
