A source told the publication that Affleck has had his eyes set on Miller ever since he announced his divorce from Garner in June.

"They're really flirty on set. Right now Ben just wants to keep things casual so he can concentrate on his children. He's not looking for anything serious," the insider said.

Meanwhile, there are reports that the "Alias" star has started dating other guys as well.

Although no one has been linked to Garner directly, a source close to the actress said that she's excited to see what lies ahead of her.

In an interview with Close magazine, the source revealed that Affleck and Garner previously went to therapy.

However, their intention wasn't to help save their marriage, but to help them accept that their relationship is over.

"The therapy she and Ben had really helped Jennifer move on emotionally from Ben and heal her heartache. She no longer feels negative about marriage and has told pals she can imagine falling in love again and settling down. She'd happily have more children too," the insider said.

In other news, it has also been confirmed that Affleck's affair with their former nanny Christine Ouzounian is completely over.

"Ben was truly sorry when he apologized to Jen, and she thought it was a very good step moving forward."
