Ben Affleck, Jennifer Garner Divorce: 'BVS' Star Moving On With Ex Co-Star Kate Beckinsale or Sienna Miller,'They’re Really Flirty on Set' Says Insider [Report]

The ex-couple Jennifer Garner and Ben Affleck are putting up a good front for their children after they announced their split publicly. Despite their amicable arrangements to co-parent their three children, they were plagued with several controversies of moving on and getting back together. Well, it seems that the "Gone Girl" actor and the "Miracles from Heaven" star are determined to take their separate lives now.

Parent Herald previously reported that the exes had a good time on Thanksgiving. Garner and the kids spent the Turkey Day with Affleck and his family. In fact, last Sunday, the "Alias" actress was spotted with her mother-in-law Christine Anne Boldt and daughter Seraphina, 6, strolling around L.A. sharing a good laugh.

However, although the "Daredevil" former couple is good at co-parenting and maintaining their healthy relationship with their in-laws, it doesn't really mean that there's a chance of reconciliation.

According to MSN, the "BVS" star has been in contact with his former "Pearl Harbor" co-star Kate Beckinsale. The two stars are good friends and were romantically linked with each other. Currently, the rumored ex-lovers are getting even closer as they spend more time together following their respective splits.

"Kate used to be madly in love with Ben. He would make her giddy with excitement any time they were in the same room ... She's turned to him for support as a friend because they've stayed in touch during her difficult time," a source told The Sun.

Although they were rumored to be an item following their time together on-set, those reports were never confirmed, per Inquisitr. Now, that both are going through a divorce after quitting from their long-relationship, will they rekindle their past romance?

The report claimed that their friends were pushing them to be a couple. However, we can't tell as to how things will turn because there are also reports linking the "Argo" star with Sienna Miller.

OK! Magazine reported that Affleck is getting cozy with Miller on the set of their upcoming flick "Live by Night." "Ben's had Sienna in his sights for a while. They're really flirty on set," one source told the news outlet. "Right now Ben just wants to keep things casual so he can concentrate on his children. He's not looking for anything serious."

In a separate report from Parent Herald, Garner has already moved on from her estranged husband. In fact, she already expressed her interest in dating again and even asked friends to help her find an eligible bachelor.
