Congrats to Mariah Carey and Nick Cannon! The happy couple renewed their wedding vows in Paris on Friday to commemorate their upcoming fourth anniversary this Monday (April 30). Too cute!

E! Online reports that Carey and Cannon have renewed their vows every year since their original wedding, making this the fifth time they've swapped their matrimonial promises.

Carey sported a white mermaid gown with black ribbon sash at her newly svelte waist. Cannon coordinated with his wife, donning a white tux, black tie and shoes and rainbow striped socks. The duo took pics in a faux proposal pose. We bet she said yes! Carey's rep shared the happy news. "Mariah and Nick renewed their vows at the summit of the Eiffel Tower in an intimate ceremony after a romantic dinner at the beautiful Jules Verne restaurant."

We're glad Carey is celebrating. It will be a welcome bit of good cheer following the tragic news of her sister's cancer.

Not only is Carey and Cannon's anniversary on Monday, but it's also "dem babies" first birthday! We can't wait to see those photos -- Moroccan and Monroe may be the cutest twins on the planet.
