"There was no tension or drama, just a lot of love and family time. Khloé and Tristan were great," a source revealed. "They hung out together with True and were chatting a lot."
"The beginning of the evening started off being all about the kids. They had a Santa Claus, sleigh and a candy shop," they continued. "All the kids were running around and completely in awe of all the entertainment."
The news comes just weeks after Jordyn Woods, who Thompson allegedly cheated on Kardashian with back in February, took a lie detector test in a bid to confirm her innocence.
Drama aside, the Christmas Eve event was one to remember with Kourtney Kardashian taking on the role of host.
Dressed for the occasion, Khloé and one-year-old True matched in gold ensembles by Bryan Hearns while Kylie Jenner and daughter Stormi arrived in emerald-hued Ralph and Russo ensembles.
For this year's party, a tradition kickstarted by matriarch Kris Jenner, the space was decked out in woodland-themed decorations with dozens of poinsettias and even an upside down Christmas tree taking centre stage.
Australian songstress Sia took to the stage to entertain guests dressed as a doll while Kanye West's Sunday Service choir also sang the night away.
But if that wasn't enough to top Christmas Eve parties across the globe, guests were sent home with a box-fresh pair of Yeezys - the Kardashian party bag of sorts.
