AceShowbiz - Jennifer Lopez and Ben Affleck continue to put on a united front for the sake of their children. The estranged pair have reunited again to attend a back-to-school event with their kids amid their ongoing divorce.

The singer/actress and the actor/filmmaker were spotted at their children's back-to-school night on Tuesday night, September 17. They were there to support their respective children at their Los Angeles area school.

According to TMZ, insiders dished that the soon-to-be exes were totally cool with each other and very cordial. Despite their friendly display, the site notes that they're still moving forward with their divorce. The source added that the estranged spouses still care for each other.

Just a few days before, J.Lo and Ben were spotted having brunch together with their children at the Beverly Hills Hotel in Beverly Hills, California. While they appeared tense in public, the couple was reportedly very cozy when the paparazzi cameras were away.

A source told Page Six of the couple's September 14 outing, "Ben and JLo are currently at the Polo Lounge at the Beverly Hills Hotel holding hands and kissing. The kids are with them, but at a separate table."

This sighting comes nearly a month after the "Marry Me" star filed for divorce from the "Argo" actor on what would have been the second anniversary of their Georgia wedding. In the filing, she cited irreconcilable differences as the reason for their split.

The two reportedly did not sign a prenup before marrying, which could potentially lead to a battle over assets, including their Beverly Hills mansion that they put up for sale for $68 million in July.

Ben has since moved to a $20 million mansion in the Pacific Palisades while J.Lo has been house hunting. She filed a legal motion to drop her husband's last name and, when stepping out on red carpet, appeared to have covered or removed a "commitment" tattoo dedicated to their reconciliation.
