The pregnant sisters starred in a new clip featuring their latest Lip Kit partnership called In Love with the Koko Kollection, which dropped in May, featuring three different shades of matte liquid lipstick and one nude gloss.
“We created them. It’s our baby together, we have eight!” Kardashian, 33, proudly told 20-year-old Jenner, who responded: “We have so many babies, who knew?”
The Keeping Up with the Kardashians siblings previously released three matte liquid lipsticks — Okurrr, Khlo$ and Gorg — as well as a gloss, called Damn Gina, for the Koko Kollection, which was released in November 2016.
In the footage, the mothers-to-be also explained that they coordinated their outfits to be in all black as wig maven Kylie shared how she chose to match with blonde hair. The YouTube video comes two weeks after Kylie and Khloé teased fans and followers with sneak peeks of their collab clip on Snapchat.
In September, the reality stars each broke the internet with their baby news.
Kardashian is expecting her first child with NBA boyfriend Tristan Thompson, 26, whom she has been dating since September 2016. Thompson is already father to a son named Prince Oliver from his previous relationship with ex-girlfriend Jordan Craig in December 2016.
“Yes, Khloé and Tristan are expecting and they are absolutely thrilled,” a source told PEOPLE at the time.
