While Witherspoon was hard at work on Wednesday, she'll be spending Thanksgiving with Tennessee, as well as her two other kids, 17-year-old Ava and 13-year-old Deacon.
ET caught up with Witherspoon's ex, Ryan Phillippe, last week, where he shared exactly how the two make it work during the holidays.
"As a divorced dad we trade off, so last year my kids and I went to my parents in Delaware, this year they will be with their mom and I am shooting a movie up in Toronto," he said, praising Witherspoon for being "healthy about how we do things." "I am going to fly down to Philly and just have a Thanksgiving with my parents and the kids get to be with Reese."
"You have to get to that point as a divorced parent, as any parent, where you’re not putting yourself first," he said. "You want the kids' experience to be its own and not like, 'Well, I need to have my time!' We have been very good about that."
