While Khloe Kardashian showed her supposed attempt to get pregnant on Keeping Up With The Kardashians, her big sister Kim revealed she really didn't want to have a baby at the time.

In fact, she was doing what she could to not get pregnant by her then husband Lamar Odom.

During an appearance on Jimmy Kimmel Live Thursday, Kim revealed the news and said, "For so long, everyone in our family was feeling really sad for Khloe [and] thinking that she wasn't getting pregnant and everyone around her was...She was not showing up to these doctors' appointments behind our back and on purpose [to not get pregnant]."

The star, who is engaged to rapper Kanye West, added that Khloe knew it was not the right time for her to get pregnant, and focused on working on her relationship with Odom instead.

However, Khloe filed for divorce from Odom last month, but Kim said she had her family to lean on during this difficult time.

"When you have a really good support system, it can be easier. It's never going to be easy, but it can be easier," she said.

Kim also dished on what it's like for her and West to live with her momager Kris Jenner and how he's dealing with it.

"He's lived with me, my mom, my sisters...So much going on. But that's why we need our time to go to Paris. We do our own thing to get away," she said.

She also revealed that 32 people go in and out of their home on a regular basis.

Kimmel joked that maybe that's why Kris' estranged husband, Bruce Jenner moved out.
