Sofia Richie and boyfriend Scott Disick are having a sexy, fun night together. The 19-year-old beauty was in total holiday spirit while goofing around in the kitchen as she rocked a raunchy Santa outfit.

Scott took to Instagram Stories to share a slew of short videos of his girlfriend, who recently swapped her blonde locks for brunette, having fun and dancing wildly in a Santa sweatshirt, skimpy white briefs and matching cozy socks. The pair appeared to be having a blast with Sofia dancing to a familiar song.

Styling her hair in a messy bun, Sofia was seen prancing around the kitchen while dancing to her dad Lionel Richie's 1983 classic "All Night Long (All Night)". Scott simply captioned it, "Night." She later started to laugh and playfully asked her boyfriend to "stop" recording.

Another video saw the lovebirds playing a game which they called "Ice trader." While staying behind the lens, the father of three threw ice cubes at Sofia, who stood across the room. The Tommy Hilfiger model giggled throughout the video while trying to catch the ice cubes.

The "Keeping Up with the Kardashians" star and his much younger girlfriend looked happy as ever, but unfortunately Sofia was not allowed to join any Kardashian family holiday events this season. The self-proclaimed Lord's ex Kourtney Kardashian reportedly "made it clear to Scott that his girlfriend Sofia is not allowed at any family holiday events."

A source previously said, "Kourtney has several issues with Scott dating Sofia and does not like it at all. Kourt has banned Sofia from meeting the kids despite how serious things are getting between Sofia and Scott. Kourtney is also trying to prevent Scott from bringing Sofia to the big annual Kardashian family Christmas party."

The source added, "Kourtney wants to maintain family tradition and she does not think Sofia fits into that ideal."
