A couple of cuties! Kylie Jenner shared an adorable throwback photo with her sister Kendall Jenner and their dad, Caitlyn Jenner, on Instagram on Thursday, December 22.

The pic shows the siblings with the Olympic gold medalist before she transitioned from Bruce to Caitlyn. Kylie, 19, captioned it simply, "because it's Thursday."

The makeup maven is gearing up for Christmas and shared some Snapchat videos on Thursday night of her besties opening gifts early, because she "just can't wait" for December 25. (While she appeared to be giving some of her friends a selection of cosmetics from her successful makeup line, one of the Keeping Up With the Kardashians star's presents was a white robe embroidered with the words King Kylie.)

The youngest Jenner sibling also shared a series of adorable Christmas throwback photos on her website, thekyliejenner.com, on Thursday that showed her sitting on Santa's knee and also wearing a festive red dress and holiday-themed decorations on her cheeks.

"Face paint, a puppy stuffed animal, chips and dip, velvet and Santa?!" she wrote. "Clearly, I was at the most lit holiday party ever, lol. I've always loved Christmas so much, I think I inherited it from my mom!"

Kylie's mom, Kris Jenner, is gearing up for her annual Christmas Eve bash and showed off her over-the-top Kandy Wonderland–themed decorations in a new video for Architectural Digest earlier this week. In addition to a towering Christmas tree decorated in red-and-white candy ornaments, Kris has a collection of personalized gingerbread houses, white stockings hung on the mantel above the fireplace, and a gigantic, metallic red statue of a bear.
