The Keeping Up With The Kardashians star and basketball player Humphries tied the knot in front of friends and family at a private estate in Montecito, CA on Saturday.
Kardashian wrote on her official website: "Saturday was completely magical and I couldn't be happier right now. I'll never forget our special day and I want to thank all my friends and family for making the day so special. I love you all."
Kardashian also posted a photograph of herself dressed in her wedding gown on the cover of People magazine's new issue. The publication is reported to have paid around $1.5 million for the photographs of the ceremony.
More than 400 guests, including Ryan Seacrest, Demi Lovato, Serena Williams and Lindsay Lohan, watched Kardashian and Humphries marry at the black-and-white themed wedding, which will air on E! as a two-part special.
Kardashian wore a custom-made Vera Wang wedding gown to walk down the aisle, later donning another two creations by the designer at the reception. Her bridesmaids and mother Kris Jenner also wore Vera Wang.
Kardashian later thanked the designer for making her "dreams come true", writing on Twitter: "Seriously @VeraWangGang thanks for making all of my dreams come true! U are a true fashion icon! I love u sooo much!!!! (sic)"
The couple were rumoured to be planning a second wedding ceremony in New York, although Kardashian dismissed the speculation earlier this week, saying the alleged event was actually a "welcome to New York party" being thrown by friends.
Kardashian and Humphries are currently thought to be honeymooning in Europe ahead of Kardashian's scheduled appearance at the MTV Video Music Awards in Los Angeles on Sunday.
Keeping Up With The Kardashians airs Sundays at 10pm on E! Entertainment Television (Sky: 151/ Virgin: 156). Kim's Fairy Tale Wedding airs Sunday 16th October and Monday 17th October at 9pm on E! Entertainment Television (Sky: 151/ Virgin: 156)
