E! News had been told that the pair were renewing their vows at the park—which made sense, considering they have done so every year since tying the knot in 2008—and a few tweets from various corners may have blown the lid off the hush-hush enterprise.
"Mariah Carey and Nick Cannon renewing their vows in front of the Castle tonight," read a tweet from MouseWait (the account keeps visitors to the park apprised of how long the lines are for each ride), which also posted a pic showing preparations for a party under way in front of Sleeping Beauty Castle.
"Happy 5th(!!!!!!) Anniversary to the Best Husband in All The Land & 2 years ago pon de delivery…," Carey tweeted earlier today. She also showed off a beautiful chandelier that her other half bought for their special day, writing, "Happy Anniversary from my Husband to me!!!!#4/30
Meanwhile, their increasingly adorable twins, Monroe and Moroccan, who were born on mommy and daddy's third wedding anniversary, turned 2 today! Mariah shared a few Vine videos, one showing the kids all dressed up for a party (or, possibly, a wedding ceremony), and two of herself getting her hair and makeup done.
And, judging by longtime Mariah pal Da Brat's excited tweets, at least some friends and family were along for the ride.
Reps for Mariah, Nick and Disneyland have not yet returned requests for comment.
