It appears the group had a pajama party as Kim sported a black robe with her hair in a slicked-back bun, while Khloé wore Christmas-themed pajamas with her hair down in loose waves. Britney opted for a yellow-and-white ensemble, and Cade had on a Mickey Mouse T-shirt with a dark hoodie and hat. In the first photo, the Toxic singer stuck out her tongue while Kimmy Kakes posed with a duck face and peace sign. She captioned it, "Calabasas nights." In the second snap, the four are sitting next to each other in bed while Brit makes a funny face and Khlo sticks her tongue out.

They reportedly met in the early 2000s and are both friends with Paris Hilton. However, the last time they were photographed together was at a 2012 Grammy Awards party. So, the hangout this week marks the first time in 13 years that Kim and Britney publicly reunited. Wow! Although the pair haven't had a girls' night in a while, Kim has kept up with Britney's life. Back in 2021, the SKIMS creator expressed her admiration for the performer after watching the Framing Britney Spears documentary that chronicled her 13-year conservatorship. Kim wrote at the time: "The way the media played a big role in her life the way it did can be very traumatizing and it can really break even the strongest person. No matter how public someone's life may seem, no one deserves to be treated with such cruelty or judgment for entertainment. ... Everyone involved in the business of shaming and bullying someone to the point of breaking them down might reconsider and instead try to show some understanding and compassion. You just never fully know what someone is going through behind the scenes and I've learned through my own experiences that it's always better to lead with kindness." It's great to see them together again! What are your reactions to the reunion? Drop 'em in the comments!
