A publicist for the pair says they renewed their vows Friday at the Eiffel Tower in Paris, France.
Spokeswoman Cindi Berger said the couple celebrated with an "intimate ceremony after a romantic dinner at the beautiful Jules Verne restaurant" just after midnight local time.
Carey, 42, and Cannon, 31, married in the Bahamas in 2008 after a whirlwind romance that began just months earlier. Carey gave birth to their twins, son and daughter Moroccan and Monroe, last April.
Cannon was hospitalized in January and later diagnosed with inflammation of the kidneys. He resigned from his New York City radio show in February to help his recovery. Earlier this month, he said he'd document his return to health on his website in a show called "NCredible Health Hustle."
