Kim Kardashian already a busy working mother-of-three.

But Kim Kardashian revealed her husband Kanye West was harassing her for more children up to seven on Sunday night's episode of Keeping Up With The Kardashians.

However, Kim, who used a surrogate to carry her third child due to medical reasons, isn't keen - and she has a very specific reason.

Kim Kardashian has complained that her husband Kanye West was eager for more kids, but she felt that the world was too unsafe.

'He's been like harassing me, we wants like seven, he's stuck on seven,' she said.

'I could never, especially like in the world we live in,' she added, saying she thought the U.S. needed tighter gun control.

The 38-year-old complained that her husband Kanye West was eager for more kids, but she felt that the world was too unsafe.

'He's been like harassing me, we wants like seven, he's stuck on seven,' she said.

'I think there's a little bit of hope in this world, if kids like this are our future,' she said.

Kim took her five-year-old daughter North to the march, and mentioned that Kanye was also there, but the rapper was not shown on camera. She then met with some survivors of the Parkland shooting to hear their views.
