The bride-to-be is clearly gearing up for her wedding to Kanye West, which will take place on 24 May — in less than two weeks — in Paris.
" Just finished my morning workout," she captioned a snap with her gymwear lifted up to show off her stomach.
The date of Kim and Kanye's big day was revealed after one of the official invitations surfaced online.
The luxury invitation, which is made of thick grey card and embossed with gold lettering, begins: "The honour of your presence is requested at the marriage of Kim Kardashian to Kanye West.
"Saturday the twenty-fourth of May two thousand and fourteen," it continues. "Details upon arrival. Black tie."
While the location of Kim and Kanye's nuptials is not on the card, it does state that there will be a glamorous pre-party the day before.
"On the eve of our marriage please join us for a dinner," reads the invite. "Friday, the twenty-third of May at six o'clock in the evening. Paris, France. Cocktail attire."
As Kim's wedding draws closer, the reality TV star has been clarifying details about her third big day.
E! News confirmed that Kim's step-father Bruce Jenner will walk her down the aisle as he did in 2011 when she married Kris Humphries.
Unlike her second wedding, however, Kim's ceremony to Kanye will be a "very small and intimate" affair.
"There are only 100 guests invited," a source told E!. "It is only their closest friends and family. The couple had to be very selective and cut it off at no work friends, no matter how close or cherished."
