Watch it go down (below)!!!
The one-time PDA lovers are now headed for divorce and there is likely NO turning back.
Actually, Nick and Mariah are getting along better now that they've split since secretly separating in May.
At least they can keep it friendly for the sake of their sweet twins??! Rumor has it that six months ago they couldn't even be in the same room together!!!
YUP. The same couple that had a Disneyland fairytale vow renewal just over a yeay ago.
We wonder WHAT changed between them, but we suppose we'll never know.
It is certainly the end of an era and Nick and Mariah's smooches will be deeply missed!
