The sisters promoted their makeup collaboration, the Kylie Cosmetics In Love With the KoKo Kollection, in a YouTube video released Tuesday—and seemingly poked fun at dual pregnancy rumors in the process. "Doing this collection with Kylie was really fun," said Khloe, who is reportedly expecting a baby with Tristan Thompson. "I don't think we expected to do it together."
"You are really easy to work with," Kylie told her, "and I feel like we just vibe."
"We totally vibe. "I don't care if I'm Kylie's older sister; I really respect that this is Kylie's business, and she built this business, so I think it's an honor to be a part of it," Khloe, 33, said. This was a full-on collab., and I loved working with her, because I got to learn a lot about [her]."
