The singers ended their two-year romance in 2018 and after a little post-split spat, they remain close - and have decided to hook up on Christmas Day to celebrate with their kid.
The One Direction star tells TV show "This Morning", "I'm going to go and see Bear, maybe cook Christmas dinner, see the family. It's the first time he really gets Christmas now. I want to see if he really gets unwrapping presents this year. Otherwise, it'll just be Cheryl by the tree again!"
