Reality star Kim Kardashian had her own mini photo shoot while on vacation in Hawaii with boyfriend, rapper Kanye West.

Posing on the beach at night in a sexy black cut-out swimsuit, Kardashian looked as though she was being snapped for a swimsuit magazine cover.

But on her twitter account, she posted the pictures with the words, 'Night swim' and 'Night shoot.'

The 31-year-old beauty is with West as he finishes tracks for his upcoming album. Kardashian and West have been dating for about four months. Earlier this week, it was reported by Radar Online that Kardashian reportedly wants her divorce from NBA player Kris Humphries finalized as soon as possible so she can marry West.

"Kim feels that Kanye is the man she is going to spend the rest of her life with, and she doesn't want to wait. Kim's deposition will likely take place in the next few weeks, but she feels nothing is going to be gained by it," a source told the celebrity gossip site.

Kardashian and Humpries married in a lavish $10 million wedding, only to separate 72 days later.

Kardashian's estranged husband even tried to serve Kanye West with a deposition subpoena in Nordstrom box at Kim Kardashian's house recently, according to the Daily News.

Earlier this week, Kardashian made her rap debut in boyfriend Kanye West's music video "Cold." The video is a mash-up of DJ Khaled's song, "I Wish You Would" and West's "Cold" and features fellow rapper Rick Ross. "Cold," previously called "Theraflu," was done in collaboration with Khaled, and has become known as the anthem in which West first publicly professed his love for Kardashian.
