Kim Kardashian West insists naming her son South is the ''stupidest'' idea.

The 'Keeping Up With the Kardashians' star and her husband Kanye West are expecting their second child, a boy, but she won't be giving the tot a moniker that is a ''lower direction'' than her two-year-old daughter's name, North.

Asked on Shaquille O'Neal's 'Big Podcast' how many times she has been asked if she will name the baby South West, she said: ''I've been asked hundreds of times. And I think it's the stupidest question, no disrespect to you.

''Why just add another direction? We're good. North is the best. I don't want to try and duplicate that with like a lower direction, you know?''

Kanye recently spoke out to defend his daughter's ''innovative'' name.

He said: ''Ya'll be calling my daughter's name weird, like, her name should be like some name that you've heard before and all that. I don't like to say that it's weird when it's innovative and fresh.

''Like I hate that, like, creatives are beat down so much and are put in a position where they can't even speak out loud, that's the reason why the world be ugly, because there's millions of beautiful colours in the world but the world is only controlled by one colour.''
