American star Kim Kardashian West is not afraid to disagree with Kanye West - but she's determined to keep things behind closed doors.

The 37-year-old reality star - who has kids North, five, Saint, two, and eight-month-old Chicago with Kanye - has been largely supportive of her husband in public, but is apparently happier to challenge Kanye on his controversial views when they're at home.

A source told People: "She lets him take the lead, and she never disagrees with him publicly. 

"She has decided that's the right move, but she isn't scared to share her disagreements with him behind closed doors."

Kim is said to disagree with her husband on a number of issues, including some of his political beliefs. 

But the brunette beauty has decided to keep their arguments private because she thinks it's the best way of "managing him".

The insider explained: "Don't think that she's afraid of him, because she's not. She's just managing him the best she can."

Recently, Kanye claimed he's a "God".

The 'Famous' hitmaker revealed he'd come off the medication he was previously using and was "fully back in mode".

Kanye said: "Those five albums that I dropped earlier were like superhero rehabilitation.

"Now the alien, Ye, is fully back in mode, off of medication, working out, breathing as much fresh air as possible, thinking, doing, being himself. 

"When I say I'm being myself, that doesn't mean I'm being Donald Trump, it means I'm being me and I'm punk and I can wear whatever I want 'cause I'm a God."

Kanye also tried to clarify his recent tweet in which he suggested he would support abolishing the 13th Amendment, which outlawed slavery.

The rapper insisted he should have used the word "amend" rather than "abolish".

He said: "Abolish was the wrong language. I misspoke by saying 'abolish'. 'Amend' is the right language. And what's beautiful about our Constitution is that we can amend it, right?"
