The guest list included:

Demi Lovato, Babyface, Vera Wang, Mario Lopez, Mark Ballas, Ciara, Carmelo Anthony, Eva Longoria and Eduardo Cruz, Ryan Seacrest and Julianne Hough, Alan Thicke, Cheryl Burke, Melanie Brown, Maria Menounos, Sugar Ray Leonard, Serena Williams, Kathie Lee Gifford, Brittny Gastineau, Greta Van Susteren, Jillian Barberie, Brody Jenner and Avril Lavigne & Scottie and Larsa Pippen.

Dina, Ali and Lindsay Lohan were also there. Lindsay was the epitome of class and wore white. The attention whore!

Kardashian wore an ivory custom-designed Vera Wang gown with full tulle skirt, basque waist and hand-pieced Chantilly lace appliqué on the bodice and train. She wore Guiseppe Zanotti shoes.

The groom wore a white peak lapel tuxedo jacket, black tuxedo pants with white tuxedo shirt and white bow tie – all by Ermenegildo Zegna – and the couple exchanged rings by Lorraine Schwartz, who also designed the engagement ring.

A headline on Kardashian’s website on Saturday said, “We Are Officially Married!”

Two of her sisters — Khloe and Kourtney, both fellow reality television stars and partners in retail and other projects — took to social media to echo the bride-to-be’s excitement.

“My sister’s getting married today!!!” Khloe Kardashian tweeted, later linking to a web posting dedicated to “Kimmie.”
