Ben Affleck and Jennifer Garner are rumored to be considering giving their troubled marriage another try amid speculation she is pregnant with the couple's fourth child.

OK Magazine reports the two have recently been spending more time together in therapy sessions, and the heart-to-heart sit-downs have been a "revelation" for them.

"It's connected them, emotionally, in a way neither of them could have predicted," a source said. Reports are after recently dining together the two "laughed and talked for hours" before putting the children to bed and ending up spending the night in each other's arms.

"After Ben helped Jen put the kids to bed, one thing led to another... and he ended up staying the night," a source said.

Earlier this summer, the two announced they were splitting after ten years, when rumors spread that Affleck had engaged in an affair with the children's nanny Christine Ouzounian.

Affleck has long denied the rumors, and word is he recently changed his cell phone number to keep Ouzounian from repeatedly pestering him.

"Christine had been calling Ben's cell phone a lot after he came back to Los Angeles," a source said. "But Ben made it obvious to Christine that he had no interest in a relationship."

Also angering Affleck were reports that Ouzounian was considering a role in the world of reality television. Rumored possibilities included stints on shows such as "The Bachelorette" or "Dancing With the Stars."

With Ouzounian apparently now far in their rearview mirror, things appear to be looking up for the once wayward Affleck and Garner.

"Ben and Jen have been spending a lot of time together, and they've decided to keep working on their relationship," a source added. "They want to see where the process takes them."
