Is there another member of the Kardashian-Jenner family expecting a child? No, but that's what Kendall Jenner made her big sister Kim Kardashian believe on the premiere episode of Kocktails with Khloé. On Wednesday (Jan. 20), Kendall prank called her sister into thinking she was pregnant and you'll never believe how Kim responded!

After some delay, Khloé finally kicked off her new late-night talk show Kocktails with Khloé on the A+E owned network, FYI. The show centers around the 31-year-old reality star as she invites friends, family, and celebrity guests over for tasty drinks, juicy conversation, fun party games, and delicious food in the kitchen.

As the night carried on, the 20-year-old model was asked to pretend like she was pregnant to get a reaction out of Kim, but what came out of the mother of two's mouth wasn't what they expected. Kendall played the prank off very well, keeping a serious voice the entire call and even making her voice tremble from time-to-time, adding a concerned effect.

"I was calling you because I wanted to tell you something and I haven't told anyone yet because I feel like you could help me figure out what I should do," Kendall said to Kim on the phone. "I am pregnant."

Kim didn't quite know how to respond to the news. In fact, she thought Kendall meant to call their mom Kris instead of her. If you thought she was going to welcome Kendall with tears of joy or congratulatory words, think again. After gasping in surprise, Kim gave Kendall a reality check of what being pregnant and being a full-time mother of two feels like for her.

Mrs. Kardashian-West, who was caring for two-year-old North and one-month-old Saint at the time of the call, reminded Kendall of the painful experiences she shared during her most recent pregnancy. Believing it was a conversation they should have face-to-face, Kim was ultimately torn about the dilemma.

"I don't know. I'm not the one to talk to. I've had the worst experience and I'm so fresh off of the worst birthing experience," Kim told Kendall. "I mean, today is not the day because I'd literally be a little more negative because I'm on like one hour of sleep because North was up all night and I was feeding her every two seconds and literally my day has been so crazy and I had no sleep and I want to die, but oh my God it's so hard!"

Kendall wasn't the only guest to grace the couch and sip on drinks. Khloé also invited rapper Snoop Dogg, estranged Real Housewives of Beverly Hills cast member Brandi Glanville, The Talk co-host Aisha Tyler, and Young & Hungry star Kym Whitley to appear on the show.

Catch more episodes of Kocktails with Khloé on Wednesday at 10 p.m. ET on FYI. The season will carry on with seven more hour-long episodes.
