What happened to all that cozy co-parenting?!

Jennifer Garner walked her girls Violet and Seraphina home from school today in LA, and we couldn't help but notice that Ben Affleck was nowhere to be seen. After he left rehab last month, the former couple were practically inseparable as they tackled their childcare duties, but he's been noticeably absent ever since a new report surfaced that he's been texting the family nanny again.

Perhaps the mother-of-three has finally had enough with playing nice? If you believe the rumors, the actress is giving her estranged hubby a taste of his own medicine by flirting up a storm with her hunky bodyguard!

“As far as Jen is concerned, there’s nothing wrong with having a little eye candy in her life. Especially given that she suffered the humiliation of Ben cheating with the nanny. Now she can get the ultimate revenge by being seen on the arm of her hot bodyguard!” a source dished to Radar.

“She can’t help but feel butterflies when he’s around. She can’t deny he’s very good-looking. It’s gotten to the point where they hang out even when he’s off the clock,” the source added.

If this is true, good for her!
