Kim Kardashian has legally changed her last name to West.

The 'Keeping Up with the Kardashians' star, who married rapper Kanye West in May, has revealed she has applied for a passport with her new moniker.

The 33-year-old beauty shared an image of her new passport photograph, taken after her appearance on 'Jimmy Kimmel Live' on Monday (04.08.14), on Instagram on Tuesday (05.08.14), with the caption: ''New passport pic #Mrs.West #NameChange (sic)''

The reality TV star, who has 13-month-old daughter North with the 'New Slaves' hitmaker first changed her name to Kim Kardashian West on her social media accounts four days after she exchanged vows with Kanye, 37, in Italy on May 24.

The brunette beauty also previously revealed she wanted to have the same last name as her third husband and daughter.

Shortly after getting engaged in October 2013, she said: ''It'll be Kim Kardashian West. Not hyphened. Maybe make [Kardashian], like, the middle.''

Kim recently said she feels like she and Kanye will ''always be in the honeymoon period.''

She said: ''I feel as though we'll always be in the honeymoon period. We always say we really like to treat each other like it's our birthday. I try to treat him like it's his birthday every single day. I think we'll always be like that.

''We always try to make life as fun and enjoyable as possible.

''We do travel, and work really hard, when we're together - and even when we're apart, we're always on the phone 24/7 - just trying to make that time as memorable as possible.''
