Jessica Simpson’s dishing on her Thanksgiving — saying she spent it with estranged hubby Eric Johnson … because, hey, co-parenting is top priority!

Jessica chatted with a photog at LAX Friday, saying Eric made sure to snag a seat at the dinner table at her mom’s … all ’cause he’s the father of her three kids — Maxwell, Ace Knute, and Birdie Mae — so there was never any doubt he’d be there.

Catch the full clip, because even with Jessica and Eric calling it quits back in January, she’s still all about family first — and she drops some legit gems on how keeping the kids’ POV front and center makes all the difference.
