The Fashion Police host was invited to Kim's bridal shower last month but canceled last minuted due to the death of her dear friend Amy Winehouse.
Odds That She'll Show: Highly likely. Since she missed Kim's shower, we're betting she'll be there for the big day.
Hip-hop power couple Beyoncé and Jay-Z were supposedly invited, according to Radar. The ladies are publicly fans of each other, with Beyoncé raving about Kim to Cosmo magazine and Kim claiming to be a fan of B, too.
Odds That They'll Show: Long shot. We've never even see them hang with her in public and Jay is super busy touring to support his new album with Kanye West.
Brittny has been one of Kim's closest friends for ages. The gorgeous gals have been running the Hollywood social scene way before Kim became super famous. In fact, Brittny was one of the first people Kim talked to about her engagement!
Odds She'll Attend: Definitely. Britt's been by her side through all the boyfriends and breakups, so she'll be right there for the big day.
Carmelo Anthony's wife runs in Kim's inner circle of BFFs. The former MTV VJ partied with Kim and co. in Vegas for her bachelorette party and even bought her leather underwear as a gag gift.
Odds She'll Show: Definitely. No way her bestie would miss her wedding!
The king of E! and Kardashian kreator Ryan Seacrest is obviously invited. He also attended Khloé's nuptials.
Odds He'll Show: Definitely, and we bet his plus-one will be girlfriend Julianne Hough.
The former Lakers player and Kris' current Nets teammate is actually the one who introduced the happy couple.
Odds He'll Show: Probably. It would be weird if the matchmaker didn't show, right?
Kim executive produced their E! series Spin Crowd stars and the guys are constantly by her side in NYC and L.A. Jonathan just signed on as the face of Wodka Vodka while Simon's been busy running Command PR. The savvy businessmen have certainly earned their spot on the guest list...in fact, they probably helped come up with it!
Odds They'll Show: Definitely. Jonathan's even gotten to see the dress already!
We're not sure who all is invited, but a team official says the Nets have been granted permission to attend their forward's big day. (Players and their teams are not supposed to be in contact during the NBA lockout; they must check with the league about events where they would be together.)
Odds That They'll Show: Likely. It could be a great team-building exercise to convince free-agent Humphries to stay in Jersey.
About a year ago, there were rumors of a romance between Kim and the rapper when they got photographed together in NYC. The truth is that Kanye was their "fashion muse," according to Khloé. The eldest Kardashian added, "Nothing happens in fashion unless Kanye blesses it."
Odds He'll Show: Maybe. He helped Kim celebrate her 30th birthday in NYC but we know Kanye's all about himself. With his new album out, we're not too sure he'll be able to attend this Kardashian event.
The unusual but solid friendship between Kim and Demi scored her a spot on Kim's bridal party guest list. The duo spent time together a few days ago at the Do Something Awards, where Kim introduced her on stage and even tweeted a picture of them blowing kisses.
Odds She'll Show: Definitely. Demi has some downtime since she's just focusing on her music instead of her Disney series these days.
LiLo reportedly attended Kim's bridal party and when asked if she was attending the wedding, her rep tells E! News he's "not commenting out of respect for Kim's privacy". Sounds like a "Yes!" to us! Let's just hope she can keep herself together at this party.
Odds She'll Attend: Definitely. What else does she have to do these days?
The Biebs met Kimmy K. last May at the White House Correspondents' Dinner and they became fast friends. They later shot a spread for Elle Magazine and most recently hung at the Do Something awards in L.A.
Odds He Shows: Probably. He's clearly secured himself a spot on the list, but don't expect him to bring along honey Selena Gomez. She's got a gig in New Jersey that night.
The tennis pro and Kardashian confidante hung out at Kim's bridal shower last month. They're super tight friends...wonder if they've been swapping workout tips?
Odds She'll Show: Highly likely.
Whether they're getting lunch or partying like it's 1920, the brunette beauties have been chummy for awhile now. Hopefully Kim's marraige turns out better than Eva's!
Odds She'll Show: Highly likely. Now that Desperate Housewives is getting canceled, Eva should have more free time on her hands. Plus, she loves a good party!
The Tinseltown twosome was reportedly on the list, according to Radar, but this seems odd to us. Sure, they both have equally famous and successful family members, but is this couple even friendly with Kim?
Odds They'll Show: Long shot.
We are not too sure exactly why, but a newly-single Jennifer Lopez may be attending the Kardashian extravaganza. Maybe Kim just doesn't want to have the biggest booty at her wedding?
Odds She Shows: Maybe. She's pretty busy these days between yachting in Miami and hitting the Hamptons with her kids and ex-hubby.
