We now pronounce you man and wife ... again!

Mariah Carey and Nick Cannon just renewed their wedding vows in Paris -- and, of course, invited the press to their special day.

The two wore white at the ceremony, where Nick got on one knee while they posed for photos in a hotel with a gorgeous view of the Eiffel Tower.

The couple's four year anniversary is actually on Monday, the 30th.

The 30th also happens to be their twins' first birthday. They grow up so fast!

"Very excited to celebrate #dembabies first birthday in a week, I can't even believe it's been a year," Mariah tweeted earlier today.

Congrats to the happy couple -- check out all their renewal pics above.
