The 'Triumphant' singer celebrated her fifth anniversary with the 'America's Got Talent' host by recommitting their love to each other in a fairytale-themed ceremony at Disneyland in Anaheim, California, reported Ace Showbiz.
The couple famously renew their vows every year on April 30, which is also marks the birthday of their twins, Monroe and Moroccan, now aged two.
Disneyland-based Twitter account MouseWait appeared to confirm the news, tweeting, "Mariah Carey and Nick Cannon renewing their vows in front of the Castle tonight."
