Kim Kardashian and Kanye West are married!

LOS ANGELES (KABC) -- Kim Kardashian and Kanye West are married!

The 33-year-old reality star and 36-year-old rapper said "I do" on Saturday evening in Florence, Italy, a source confirmed to ABC News. The source said Kardashian wore a white Givenchy gown.

The couple were married in the private ceremony before family and friends, according to E! News. The bride's sisters made up the bridal party, and stepdad Bruce Jenner walked her down the aisle, the story said.

On Friday, designer Valentino hosted pre-wedding brunch for the couple at his Château de Wideville, just outside of Paris. The couple then held a lavish party at the Palace of Versailles that included carriage rides, fireworks and a performance by Lana Del Rey, according to E! News. The guests were flown to Florence Saturday morning to watch Kardashian and West exchange vows at the Forte di Belvedere.

Celebrities reportedly in attendance included Kardashian's BFFs Larsa Pippen and La La Anthony (with pro bball husbands Scottie Pippen and Carmelo Anthony), Oscar-winning director Steve McQueen, designer Rachel Roy, celebrity hairstylist Michael Silva, music producer Rick Rubin, Jonathan Cheban and "Girls Gone Wild" creator Joe Francis.

This is the first marriage for West and the third for Kardashian, who was previously married to professional basketball player Kris Humphries for 72 days in 2011 and before that, to music producer Damon Thomas. The couple share a daughter, North, who was born last June.

West proposed to Kardashian on her 33rd birthday this past October. He rented out San Francisco's AT&T Park to pop the question, with 50 musicians playing as family and friends streamed out of the dugouts.
