Kim Kardashian refuses to tell her friends where she is getting married until they arrive in Paris.

A source told HollywoodLife.com that the 33-year-old beauty "has not sent out any invites yet" because she wants to keep the location a secret for as long as possible.

The insider said that 90 guests will soon receive a card printed with "a date and Paris" and will only find out where the couple will exchange vows when they check in to their chosen hotel in the city.

Meanwhile, Kim and Kanye have finally narrowed down options for what she will wear to walk down the aisle.

The insider said: "She's actually deciding between a custom Lanvin, and Monique Lhuillier gown. She wants to feel like a princess, but have it be form-fitting too. Don't expect some poofy dress like she wore when she married Kris [Humphries]. Think ultra chic. Kanye is involved in every part of the process."

A source previously claimed that Kim and the 'New Slaves' rapper, 36, will have a private civil ceremony in her mother Kris Jenner's office in Calabasas, California before flying to Paris, as French law requires foreign citizens to live in the country for 40 days before they tie the knot.
