Kim Kardashian and Kris Humphrey's royal wedding will be underway shortly, and the extravagant affair will be chock full of A-list celebrities.

Although Kim reportedly had to cut 50 people from the guest list per order of the fire department, the unvitees are believed to have been family members of her stepdad, Bruce Jenner. Because why have family at your wedding when you can have famous people instead?

Among the lucky A-list guests expected at the Montecito, Calif., nuptials are Eva Longoria, Dancing With The Stars' Julianna Hough, Serena and Venus Williams, Nicole Richie, Ryan Seacrest, Kelly Osbourne, and possibly Justin Bieber. And of course, the extended Kardashian clan!

People magazine has bought the exclusive rights to photographs of the wedding -- for a sum as high as $1 million -- and the wedding will air as a special on E! in October.
