Those who made the list were treated to a gourmet, four-course meal prepared by Hollywood chef to the stars Wolfgang Puck. Reception entertainment included performances by Robin Thicke, who sang his hit "Angels" for the couple's first dance, and the legendary R&B band Earth, Wind and Fire.
To top it off, guests were treated to a towering cake from famed Los Angeles bakery Hansen's, a $15,000 creation inspired by the real royal wedding of Prince William and Kate Middleton. The reportedly 6-foot tall cake included 10 layers and a decadent, chocolate chip frosting, the bride's favorite.
Continuing in the tradition that started when exposure through a reality TV show turned into a family business empire, Kardashian is cashing in -- big time -- on her weekend wedding to Humphries.
She wore white down the aisle, but Kardashian is being so well paid for her lavish nuptials that she'll end up in the black.
The wedding cost an estimated $500,000, but according to The Hollywood Reporter, the bride was paid $1.5 million by People magazine for exclusive rights to photos of the event.
The magazine apparently paid the pair an additional $300,000 for exclusive rights to pictures of their engagement announcement earlier this year.
And OK! magazine reportedly paid $100,000 for exclusive rights to photos of the bridal shower.
And that's not all. Here are a few other ways the reality TV family is saving, and earning, on the wedding:
The bride wore a $20,000 Vera Wang bridal gown. She didn't pay for it, reports say.
Her 20-carat Lorraine Schwartz diamond ring, valued at a reported $2 million, apparently cost the groom a fraction of that.
Posh Los Angeles' bakery Hansen's Cakes apparently gave Kardashian and Humphries their $15,000 wedding cake.
"She's certainly not the first (celebrity) to capitalize on her wedding and photos and the press to get everything paid for and more," marketing expert Ryan Schinman, chief of Platinum Rye Entertainment, told the Associated Press.
"It's the first that feels a little commercial," he said. "But from what everyone sees, she's very much in love, as long as her fiance doesn't mind one of the most special moments in their lives being followed and shared with the rest of the world."
So why does Kardashian have so many luxury brands and top merchants lining up to give her free stuff?
Celebrity event producer Tony Schubert told The Hollywood Reporter that because Kardashian is viewed as a "tastemaker" by so many brides-to-be, many are eager to be associated with her.
The wedding will be broadcast on E!, the network that airs the family's hit reality show, "Keeping Up With the Kardashians," as well as hit spin-offs featuring her sisters, Kourtney and Khloe.
E! will air "Kim's Fairytale Wedding: A Kardashian Event" Oct. 9 and 10, and the network is expecting it to be a ratings bonanza. After all, the wedding was one of the most talked-about events of the social calendar this year, right up there with the royal weddings in Britain and Monaco.
Some have even dubbed Kim Kardashian America's reality TV princess.
The Kardashian women are so popular that they have parlayed their reality TV success into fashion lines, fragrances and television endorsements that are worth millions. Under mother Kris' savvy management, they reportedly earned $65 million last year.
E!'s airing of Khloe Kardashian's 2009 wedding to Lamar Odom was then the most-watched broadcast in the network's history, drawing more than 3 million viewers.
On Sunday morning, the newlyweds were spotted leaving their hotel and will reportedly head to Bora Bora for their honeymoon.
