Jennifer Garner's Boyfriend Jealous Of Ben Affleck? Truth Behind Breakup Rumor

"Justice League" star Ben Affleck and Jennifer Garner's relationship may long be over, but the ex-couple still appear on tabloid covers due to unproven claims about their "romance." And the latest round of rumors plaguing the pair suggested that Garner may be planning on breaking up with new boyfriend John Miller because he's jealous of her ex.

Rumor-debunking site Gossip Cop recently shut down the rumor Garner and Miller may be parting ways soon due to the latter's jealousy of her closeness with Affleck. A source close to Garner told the outlet that there is no truth to the rumor.

Gossip Cop's report comes after the National Enquirer recently put out an unfounded story claiming Miller confronted Garner in jealous outrage over how much time she has been spending with Affleck since they finalized their divorce in October. An unnamed source claimed in the report that Garner was unimpressed by the CaliGroup CEO blowing up on her and may now be contemplating on ending it with him.

Among the many grievances Miller has with Affleck, as claimed by the so-called insider, was that he believes the actor has been "taking advantage" of Garner who has been supporting him in his journey to get sober. Affleck reportedly shows up "whenever he wants to" and speaks to Garner every day.

The report went on to claim that Garner would choose to dump Miller rather than stop spending time with Affleck. She reportedly still considers Affleck her family as he is the father of her kids and doesn't want to throw that away just because Miller may be uncomfortable with their closeness.

Meanwhile, Garner and Miller have also slammed the split rumors, albeit indirectly. Last week, the couple was spotted having breakfast together in Santa Monica just shortly rumors of their breakup first surfaced.

According to People, Garner and Miller's relationship is still casual, and the couple is enjoying their time getting to know each other. As such, this doesn't seem to support the claim that Miller would want Garner to focus all her attention on him. Garner and Affleck also share three children together: Violet, 12, Seraphina, 9, and Samuel, 6. It would be inevitable for the two to spend a lot of time together as they co-parent their kids.

"She doesn’t call him her boyfriend," a source told the magazine. "But she loves getting attention from John. They have fun together and it’s easy."

This wouldn't be the first time that the National Enquirer has published made-up stories about Garner and her beau. In November, the tabloid claimed that Garner and Miller were expecting a child and that this what the reason why she and Affleck decided to finalize their divorce. However, Gossip Cop also refuted this story.
