Ben Affleck and Jennifer Garner have been “spending more time together than ever since they divorced,” a source exclusively tells Page Six.

The “Batman” star and the “13 Going on 30” actress — who were married for 10 years, from 2005 until 2015 —  “are closer than they’ve ever been since their divorce.”

“Particularly since Ben’s divorce from Jennifer [Lopez] and with the LA fires and everything going on,” Affleck and Garner “have found themselves leaning on each other more than ever” the insider says.

“They really do have a close bond,” the source tells us of the exes who coparent their three children: Violet, 19, Seraphina, 16, and Samuel, 12.

The Oscar winner and the Emmy nominee, both 52, “know not all exes get along as well and they feel very grateful that they have such an amazing relationship.”

According to the insider, “Things between Ben and Jen were understandably rocky for a little while when they first divorced.”

“They shared custody and were amicable when it came to situations involving their kids but over the years they’ve really built a close friendship and are on the same page in a lot of ways.”

Affleck and Garner “feel like it’s only in everyone’s benefit involved to have a good relationship including themselves and their kids.”

Last month, the “Alias” star invited the “Good Will Hunting” actor to celebrate Christmas as a family with her and their three children.
