Kim Kardashian is remaining tight-lipped when it comes to rumors her sisters Khloe Kardashian and Kylie Jenner are both pregnant.

The 37-year-old Keeping Up with the Kardashians star appeared on The Ellen DeGeneres Show on Wednesday to discuss her new fragrance, her third child on the way with husband Kanye West via surrogate, and more.

But Kim probably could have predicted her interview wouldn't end without receiving some questions about Khloe and Kylie, who have yet to publicly address or confirm news they are each expecting their first child.

"Okay, I'm going to break it down. This is how we work in the family," began Kim, whose baby is due in January 2018.

"When there are lots of rumors, we have these family group chats, and we threaten each other's lives if we speak for the other one. So, for the safety of my life, we just decided that there's so much going on, we respect each other's right to speak for themselves."

Kylie, 20, is reportedly expecting a baby girl -- just like Kim -- with her boyfriend Travis Scott, a 25-year-old rapper. There is also speculation Kylie and Travis are engaged.

Meanwhile, Khloe, 33, is allegedly pregnant with a baby boy. Khloe is currently dating Ohio-based NBA player Tristan Thompson, whom she's head over heels in love with.  

"So I will speak about myself," Kim concluded on The Ellen DeGeneres Show. "And hopefully they can come on and address whatever rumors you might have."

Ellen then joked about wanting Kim's sisters to appear on her show the very next day to set the record straight.

This past weekend, Kim celebrated a floral-filled baby shower on Saturday. Reports circulated that Kylie threw herself a pajama-themed bridal shower at her home the very next day and all of her family attended.

Kylie and Khloe have both hinted about being pregnant on social media, but it's unclear why they are both staying silent in the press. The women have also been photographed recently with their baby bumps arguably showing.

But one thing is for sure at least! Mom of three, Kourtney Kardashian -- who is dating young model Younes Bendjima -- is not having another baby.
