The couple split in June but they want their children to have a wonderful Christmas with both their parents.
A source told E! News:”They will be together as a family. They continue to put the kids first and spend time with each other for the sake of their children.”
And the former couple – who are said to be ”in a good place right now” – are planning to leave Los Angeles for a festive break in snowy Montana.
It was previously claimed Ben, 43, and Jennifer are ”committed” to parenting together and putting their differences aside for the sake of their kids.
A source said: ”They are a unit. They are all about the kids and making sure they are OK. They are committed to parenting together.”
Even while Ben has been shooting the upcoming film Live By Night in Boston, he ensured he made regular trips back to Los Angeles to see the children.
The source said: ”[He] has spent every possible hour of the day working. He’s the first to arrive and the last to leave.”
