Since Thursday, they've been taking to social media, sharing happy and poignant moments with their fans.
The Beckham family, for example, is celebrating by going low-key in the U.K. Victoria Beckham kicked off the holiday by taking her youngest, Harper, 4, to see "The Nutcracker" at the Royal Opera House in London and then the family visited the gravesite of deceased family members.
"Merry Christmas Nan & Grandad we all miss you especially these 4 not so little kiddies anymore ..." David Beckham wrote on Instagram. "Grandad Cruz is sitting in your favorite chair every day , Nan Harper & Brooklyn are missing your bacon sandwiches and grandad Romeo is happy cause Arsenal are ahead of spurs in the league ... We miss and love you. Merry Christmas."
