Recently, the mogul went live on Instagram to answer some of her followers' questions. When one follower asked, "Can we also get a collab with Kendall?" she made the shh gesture with her finger, winked at the camera, and explained why that hasn't been able to happen in the past. “You know Kendall was in a contract for a really long time, so I couldn’t do a collab with her,” she said, referencing her older sister's beauty partnership with Estée Lauder . “That’s the only reason why I didn’t collab with her.” Then, she hinted: “But, you know, we worked it out.”
