This is every wife's worst nightmare!

Ben Affleck has reportedly been dating the nanny he and estranged wife Jennifer Garner hired to look after their children this spring, Us Weekly reports. The 28-year-old woman named Christine Ouzounian was fired once the A-list actress discovered the romance, but the Batman star continues to see her behind closed doors. How cliche can he possibly get?!

"They would hang out without the kids. And they were very flirty," a source close to Ouzounian dished to the mag. Umm, if this poor little maid has a prayer of this working out, the last thing she wants to do is have all her friends blabbing to the media!

The pair allegedly spent time together at the Boston hunk's L.A. rental on July 17, and have been in constant contact over text, email, and phone. The bubbly blonde is so stoked about her new relationship, she is already telling friends she thinks it might be serious! "She says Ben really, really likes her. She’s saying this is true love," another insider added. We expected him to date a supermodel next, not a woman on his payroll!

Below is a pic from her LinkedIn account!

UPDATE: Affleck's reps are shooting down the story. "All allegations of a romantic relationship are baseless and untrue," the rep told Us.
