Um, that's nice! Kim Kardashian and Kanye West are so desperate to give their 20-month-old daughter North West a sibling that they will get frisky as many times as they can in a day — and own up to it.

As seen in the above preview, Kardashian admits how much she and the rapper have been trying to conceive in an upcoming season 10 episode of Keeping Up With the Kardashians.

"I've been having sex 500 times a day," Kardashian, 34, says nonchalantly to sister Khloe Kardashian. Not missing a beat, Khloe throws her head back with a look of disgust. "Ugh!" she groans.

In an upcoming episode, Kim and Kanye, 37, show how determined they are to have another baby by leaving in the middle of a photo shoot to have a bathroom quickie.

"I was like, 'I'm ovulating today!' So I made him come to my photo shoot," Kim explained to Khloe, 30. She added in a confessional: "You know what, I don't feel bad about that for one second. You gotta get it in where you can get it in." 

In the new season, Khloe also discusses how things ended with her ex French Montana, and Bruce Jenner admits that he feels a separation between the Kardashian and Jenner families.
