The cat's out of the bag.
Following weeks of buzz about when Kim Kardashian
will say "I do" to Kris Humphries, PEOPLE got a sneak peek at the wedding invitation, confirming the big date: Aug. 20.
Kardashian, 30, and the New Jersey Nets player, 26, will tie the knot in Montecito, Calif., and celebrate with (what else?) a black tie affair.
The couple's wedding invitations were designed by Lehr & Black, who also created invites for Kim's sister Khloe and her husband Lamar Odom, Gwen Stefani
and Gavin Rossdale, and Fergie
and Josh Duhamel
, among others.
The invite, which arrived at guests' homes housed inside its own box, is embellished with hundreds of jet black hematite crystals.
The couple got engaged
in a most elaborate fashion on May 18, complete with a 20.5-carat engagement ring.
"It was everything I ever dreamt of and more," Kardashian has said
. "I think when you know ... you know."
