Kim Kardashian revealed that her sister Khloe Kardashian was not willing to take up fertility due to her troubled relationship with husband Lamar Odom.

Kim appeared Thursday on “Jimmy Kimmel Live,” where she talked about the divorces and separations in her family. She reportedly told the show’s host, “For so long everyone in our family was feeling sad for Khloe, thinking that she wasn’t getting pregnant and everyone around her was. And the whole time she wasn’t trying [to get pregnant].”

She continued by saying, “She wasn’t showing up to these doctors appointments behind our backs on purpose, and she just knew it wasn’t right [to get pregnant at that time].”

Khloe filed a divorce in December after reports of Odom’s cheating, alleged drug arrests and a DUI arrest.

"So now we understand it and we understand her decisions, it's very clear,” Kim reportedly told Kimmel on the show.

Khloe’s fertility issue was a storyline on “Keeping Up with the Kardashians,” and became a big concern for everyone around her.

Kim later clarified her comments on the show through an extended tweet on Friday: “I'm so tired of people twisting my words, Khloe did start fertility and she wanted to have a baby, but I believe in the middle of the process she realized timing wasn't good based on what was going on with her relationship. She was not ready to tell us everything so she stopped treatment without telling us.”
