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 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.
