Jennifer Garner really doesn't like to talk much about her private life to the media (unless of course she's promoting a new movie), yet there are plenty of rumors that state that something is going on in her on-again, off-again relationship with ex-husband Ben Affleck. And if that weren't enough, sources say that the actress is always calling on her ex-boyfriend Michael Vartan whenever she's having problems with Affleck.

In fact, there are even rumors that say Affleck is concerned that Garner might be secretly having a side relationship with Vartan behind his back. Of course, this complicates matters even more between them as Garner and Affleck announced their separation back in June of 2015, but are yet to file any divorce papers.

"Ben thinks something is going on with her and Michael," one source told Radar Online on Tuesday, adding, "but he doesn't know if it's just manipulative to piss him off or if it's legit they would like to get back together."

The insider noted, "She's always crying on Michael's shoulder," and that Affleck has been increasingly suspicious, especially since Vartan recently split with his wife, Lauren Skaar.

Of course, all the parties involved have not made any comments about the rumors. What's more, Affleck and Garner were spotted getting very cozy with one another while they were out and about in Paris last month with their three kids.
