You can call her Mrs. West.
Kim Kardashian is officially Mrs. West.
Two and a half months after saying “I Do,” to Kanye West in a lavish 
ceremony in Florence, Italy, the reality star formally took her 
husband’s name on Tuesday (August 5).
Of course, she’s been calling herself ‘Kim Kardashian West’ on 
Twitter and Instagram for a couple months now, but it wasn’t official 
until she got all her paperwork in — including a new passport with a new
 photo.
And in case you had any doubts, Kim Kardashian West’s passport 
photo is absolutely hotter than yours.

Kim said she’d be taking Kanye’s surname — and keeping Kardashian as 
her middle name — all the way back in October, shortly after he proposed
 with a 15-carat ring and in San Francisco’s AT&T Park.
