Kylie Jenner, Khloe Kardashian Joke About Their 'Many Babies'

These sisters aren't naïve to their fans' interest in their personal lives. After all, they've built their careers on it.

In a video posted on Kylie Cosmetics' YouTube page, Kylie Jenner and Khloé Kardashian tried out the lip products in their recent makeup collaboration, the In Love With the KoKo Kollection. After playing around with the new colors, which are mostly named after Khloé's nicknames for other people, the two joked about the many cosmetics products they've worked on together.

"We created them. It's our baby together," Khloé, 33, told Jenner. "We have eight!"

"We have so many babies," Jenner, 20, responded, laughing. "Who knew?"

As Nicki Swift previously reported, rumor has it that Jenner is expecting a baby girl with boyfriend Travis Scott. Khloé, on the other hand, is reportedly pregnant with boyfriend Tristan Thompson's baby.

And, as if those weren't enough pregnancies to shake up the next few seasons of Keeping Up With the Kardashians, older sister Kim Kardashian is also expecting a child via surrogate.

Man, it really is hard to keep up with this family. While we wait for the sisters to confirm their pregnancies, read up on why we're worried about Jenner's baby.
