The couple tied the knot Saturday night on a private estate in Montecito, California, her rep confirmed to E! and People.
Among the 440 guests: Kim's reality show executive producer Ryan Seacrest and his girlfriend Julianne Hough, her "Dancing With the Stars" partner Mark Ballas and his date Cheryl Burke, her stepbrother Brody Jenner and his girlfriend Avril Lavigne, dress designer Vera Wang, pop stars Demi Lovato and Ciara, NBA couples Carmelo Anthony and La La Vasquez and Scottie and Larsa Pippen and Dina, Ali and Lindsay Lohan.
Some of the more unexpected names included Greta von Sustren, Alan Thicke, and Kathy Lee Gifford.
As reported, the bride wore a Vera Wang wedding gown. People described the dress as having "full tulle skirt, basque waist and hand-pieced Chantilly lace appliqué on the bodice and train." Despite being her second wedding, Kim stuck to traditional ivory. Guiseppe Zanotti shoes completed her look.
The groom wore a Ermenegildo Zegna tux with a white tuxedo jacket and black tuxedo pants. His bow tie was white.
Kim's sisters Kourtney and Khloe, also clad in ivory, served as maids of honor, while sisters Kylie and Kendall Jenner were bridesmaids. The ring bearer was Kim's nephew Mason Disick, Kourtney and Scott Discik's son.
The couple sealed their vows with Lorraine Schwartz rings (Schwartz also designed Kim's $2 million engagement ring) and of course, a dazzling kiss (as E! cameras rolled).
The groom changed into a traditional black tuxedo for the reception. The bride had two more dress changes, both Vera Wang gowns.
Guests dined on a meal by celebrity chef Wolfgang Puck, and later a towering black and white wedding cake by Hansen Cakes.
Unfortunately, no photos were made public -- People bought the exclusive rights for a reported $1.5 million. The wedding issue is expected to hit newsstands Friday.
E! will footage from the wedding Sunday night, which TooFab will have for you Monday morning as well.
