The two said that even though they were no longer romantically involved, they were committed to coparenting their kids together.
Well, yesterday was Chris' birthday, so Gwyneth took to Instagram to wish him well. And her caption has some people cheering — and others raising their eyebrows.
"Happy birthday my brother. Thank you for giving me these two. 💖," she wrote, referring to their two kids, Apple and Moses.
Some commenters thought referring to an ex as a "brother" was weird.
