Kim Kardashian has axed about 50 unlucky guests from the invite list for her over-the-top wedding Saturday to NBA stud Kris Humphries. Sources say that due to space restrictions at the venue — the spacious Montecito, Calif., home of Google’s Eric Schmidt — the reality-TV diva has disinvited a number of guests, including some family members of Bruce Jenner’s sister, Lisa. Kardashian has also instituted a strict “no plus-one” policy.

But while stepdad Jenner’s relatives have been dissed, Justin Bieber, Demi Lovato, and Serena and Venus Williams are all expected to make the cut, as are some of Humphries’ Nets teammates. Meanwhile, Kardashian has inked a $1 million deal with People magazine for exclusive photos of the blessed day, which will also be broadcast as a four-hour E! special. Kardashian still has to pick one of three custom-made Vera Wang wedding gowns, each costing up to $25,000, and four pairs of custom-made Louboutins. A rep for Kardashian said, “No comment.”
