'It affects my soul when your pictures are too sexy': Kanye West voices his last-minute disapproval over wife Kim Kardashian's 'underwear'-style Met Gala dress on KUWTK

Kanye West's concerns about wife Kim Kardashian's sexy dress nearly ruined her Met Ball appearance.

Kim, 38, had spent eight months perfecting her Thierry Mugler look for the Costume Institute Gala in New York City, but was left 'anxiety' ridden when her husband criticised her appearance at the last minute.

The rare argument between the couple, which took place ahead of the annual costume gala back in May, was revealed on Sunday's episode of Keeping Up With The Kardashians. 

However, Kanye made it clear he wasn't a fan of his wife's impossibly tight corseted look, which prevented her from sitting down or going to the bathroom.

The 42-year-old rapper frowned at the underwear style of her dress, announcing at her last fitting that it didn't match with his personal evolution from being a single guy to a married man.

I just made this transition from being a rapper, looking at all these girls, looking at my wife,' he mused. 'Like, ''Oh, my girl needs to be like the other girls, showing her body off'.

I didn't realize that that was affecting my soul and my spirit as someone that's married and loved, and the father of now, what—about to be four kids?, Kanye said.
