Carey, 43, met her husband Cannon, 32, via horse-drawn crystal carriage with the Sleeping Beauty Castle serving as the backdrop. The bride dressed in all white with a strapless corseted bodice and chiffon skirt, while her Prince Charming wore a full dress military uniform.

The day also marked the second birthday of the couple's twins Moroccan and Monroe, who played a big part in the ceremony.

The 2-year-old brother and sister dressed like mommy and daddy, nearly stealing the show while walking down the aisle. Moroccan couldn't seem to sit still until Carey comforted him with a pacifier.

Earlier in the evening, Moroccan and Monroe celebrated their second birthday with 150 guests in the newly opened Fantasy Faire section of the park. Disney princess characters joined with Mickey and Minnie Mouse to celebrate with the children.

"We've been through so much in just the last five years," said Cannon. "Even me last year being hospitalized and with kids ... to have a teammate in this game of life is amazing."

Since marrying in 2008, Cannon and Carey have renewed their vows every year to celebrate their anniversary. Last year they renewed their vows at the Eiffel Tower in Paris.
