Her divorce from troubled Lamar Odom was finalized last year.
And Khloe Kardashian reveals in Sunday's episode of Keeping Up With The Kardashians that she didn't seriously try to get pregnant because she was so concerned for the future of her turbulent marriage.
In a clip of the season finale from E! Khloe goes to a fertility clinic to see if she can be a surrogate for sister Kim, 36, to allow her to have a third child with husband Kanye West.
When the doctor asks Khloe, 32, if she's ever tried to get pregnant, the reality star gives a very interesting response.
'I fake tried. I was married but I knew the circumstances weren’t the healthiest, so I just kept pretending I was doing it.' she said.
Khloe then opened up about her relationship with the ex NBA player, who she married in 2009 after just one month of dating and separated from in 2013.
In a confessional to E! cameras, she said: 'When I was doing my fertility treatments, they were more so for Lamar. I had to stop cause there was much deeper stuff that was happening in our marriage.
'I knew that it wasn't the right situation to bring a child into, and I think I've done a lot of covering up for him, like even when it made me look like I was the problem. But I was fine taking on that burden on my shoulders because he had a lot of other deeper s--t to deal with.'
Khloe split with Lamar, 37, in 2013 because of his drug addiction issues and having discovered he'd been unfaithful.
Their attempts to start a family were well-documented, including on their spin-off show Khloe and Lamar as well as reports of Khloe visiting a fertility specialist in 2012 before their relationship fell apart.
However, in 2014 sister Kim let slip that it was all for show because Khloe knew their marriage was in trouble.
'She wasn't showing up to these doctor appointments on purpose and behind our backs because she knew [the marriage] wasn't working.' she revealed to Jimmy Kimmel.
Khloe is now dating Cleveland Cavaliers player Tristan Thompson.
The Keeping Up With the Kardashians season finale airs on E! Sunday at 9pm ET available to stream on hayu in the UK & Ireland.
