Kim Kardashian West's son Saint is her "twin".

The 36-year-old American television personality believes her and 16-month-old child have the same personality and she claims the pair of them are both "so sweet", whereas her three-year-old daughter North has the same qualities as the 'Selfish' author's husband Kanye West.

Speaking about her brood on 'The Ellen DeGeneres Show', which will air on Thursday (04.27.17), the raven-haired beauty said: "He's my twin. He's literally my twin personality. He's so sweet. And he's just such a good good boy. Just such a good person.

"[North] She's really really smart, actually. She knows how to outsmart us -- if she thinks she does. But she is Kanye's twin. Same personality, says the same wild things. Those two."

And the 'Keeping Up With the Kardashians' star has revealed her oldest child will often bully her brother because she is "so jealous" of him, especially when he would nestle into the reality star's chest to be breastfed.
