And they said it wouldn't last!

Mariah Carey, 42, was a vision of love when renewing her vows (again) with husband Nick Cannon, 31, Friday in Paris — with the Eiffel Tower beaming behind them.

They also renewed their vows last year in the hospital where their twins, Moroccan and Monroe, were born. They also renewed them the year before.

"I have to do it every single year," Nick told Us Weekly. "If you were married to Mariah Carey, you'd want to marry her every year too! I just have to keep doing it to make sure it's real."

The couple's four-year wedding anniversary is officially this Monday, April 30. Monday also marks the first birthday of their twins.

Check out photos of the happy couple here. Can't wait to hear how much that diamond necklace cost. Wowza!

Anyway, happy birthday to Dem Babies — and congrats to Mom and Dad!
