One sweet day proved not enough for Mariah Carey.

Four years after getting hitched to Nick Cannon, the pair decided to head to France to renew their vows.

Handily they managed to factor in a quick photocall first.

Wearing matching white outfits Mimi and Nick-Nick smiled happily.

And not only did they share a 'we're so in love' quick kiss - Nick even got back down on one knee for a mock proposal.

The couple then headed to the Paris' famous Eiffel Tower - where they said 'I do', and all that, all over again.

The pair got wed the first time in 2008 and they have two children together.

Clearly it looks like they'll stand the test of time - which we like, if this is how they celebrated their fourth wedding anniversary though, we can't wait to see what they'll do when it comes to their tenth!

Congrats Mr and Mrs Carey-Cannon!
