But during a preview for this Sunday's Keeping Up With The Kardashians, Kim Kardashian revealed she didn't know if her relationship with Kanye would last when she got pregnant with North.
The reality star gave birth to their first child in June 2013, almost one year after they started dating.
In the preview, Kim said: 'When I got pregnant with North, I had no idea if Kanye [West] and I were going to end up together.'
The brunette explained: 'I was like, "We can break up, but let me just at least have some sperm so I can have another one," so I could have siblings.'
Kim said: 'I mean, I would want all my four kids with the same person.'
The candid remarks came after she told pal Larsa Pippen that Scott Disick wants a fourth child with Kourtney, even though they are not currently in a relationship.
