They do – again!
In a photo shoot beforehand, Carey is beaming in a stunning white mermaid dress with spaghetti straps and a black bow at the waist as Cannon, in a white suit and black tie, locks his eyes with hers.
“Tonight was an incredible night,” the singer Tweeted. “I can’t express how amazing it was to renew our vows in Paris at the top of the Eiffel tower.”
The couple have much to celebrate beyond their four-year anniversary, which falls on Monday. Along with enjoying nearly 1-year-old twins, Cannon appears to be on the mend from frightening health problems, including kidney disease.
After leaving the hospital in January, Cannon called Carey his “hero” and “the virtuous person who is my angel.” Carey returned the compliment by telling him he was her “incredible husband” who, despite his struggles, was still “all strong and healthy and big.”
