Kylie Jenner posted an Instagram photo Sunday of her, sister Kourtney Kardashian and Bailon all together, with the caption, "cause we are sistersss" (a reference to a song from Bailon's former girl group, the Cheetah Girls).
Kourtney also shared a snap from their meet-up, writing, "Reunited best friends lol."

"I kind of called it my Eat, Pray, Love journey," she said in October. "I went to Paris to study fashion, photography, and French language. I just kind of had a self discovery thing, and I'm still on that journey. I'm having a good time."
