Entertainment Tonight: Mariah & Nick Renew Vows

Global superstar Mariah Carey and her husband, actor/comedian Nick Cannon, exclusively invited ET's Nancy O'Dell to celebrate the renewal of their vows on their 5th wedding anniversary at a lavish private ceremony at Disneyland in Anaheim, Calif. on Tuesday, April 30. Mariah and Nick also celebrated the 2nd birthday of their twins, son Moroccan Scott and daughter Monroe, at a prince and princess-themed party, which took place in the park before their ceremony.

The couple shared the details of their elaborate ceremony exclusively with ET. Carey slipped into a princess-inspired bridal gown for the event at the well-appointed Dream Suite, tucked away above the Pirates of the Caribbean attraction. From the suite, Mariah and Monroe were picked up in a horse-drawn Crystal Carriage that took them to Main Street where they were greeted by Nick and Roc. They walked down the aisle as a family to Sleeping Beauty Castle which served as the backdrop for the outdoor ceremony.

The twins sat in the front row to witness the vow renewals which were themed, "Do you believe in fairy tales?" Immediately after the ceremony, there was a burst of fireworks, which was a surprise for Carey.

The Royal Footman from Cinderella, Major Domo, served as the Master of Ceremonies for the evening and escorted the approximately 250 guests to Fantasyland for a champagne toast and reception DJ'd by Cannon. The space was adorned with 15,000 blooms imported from South Africa, Holland and France and 10,000 crystals. Guests were able to take advantage of the park being closed to the public and ride the famous Matterhorn Bobsleds rollercoaster, the King Arthur Carousel and peruse the Peter Pan and Snow White attractions.

At the end of the evening, Major Domo escorted guests back through the castle where the Crystal Carriage met the couple to return them to the Dream Suite.

Earlier in the evening, Moroccan and Monroe celebrated their 2nd birthday with 150 guests in the newly opened Fantasy Faire section of the park. Disney princess characters as well as Mickey and Minnie Mouse celebrated with the children.

Carey, 43, and Cannon, 32, have renewed their vows every year to celebrate their anniversary. Last year they renewed their vows at the Eiffel Tower in Paris.

The American Idol judge also took to Instagram to share a few pics on her fifth wedding anniversary. One caption reads: "Happy 5th (!!!!!!) Anniversary to the Best Husband in All The Land & 2 years ago pon de delivery room=luckiest Mommy in The WORLD!"

The couple were married on Windermere Island in the Bahamas on April 30, 2008, and on April 30, 2011, they welcomed "dem babies," twins Moroccan and Monroe.
