What better place to renew your vows than in Paris? That's exactly what Mariah Carey and hubby Nick Cannon did to celebrate their fourth year as husband and wife on Friday, three days before their actual anniversary, April 30 -- which also happens to be the first birthday of their twins Monroe and Moroccan. With the Eiffel Tower as their backdrop, Carey -- in a white satin mermaid-style gown with a black bow -- beamed as a white suit-clad Cannon got down on one knee, took her hand, and looked into her eyes during the intimate ceremony at La Maison Blanche hotel.Before they jetted off to the French capital, the "America's Got Talent" host hinted that he and his superstar wife were planning something "special and unique" -- and it looks like they achieved their goal with the lavish celebration.
