All turned out to be well, with Mariah tweeting, "They almost came on 3/27- happy anniversary in deed!!! We have a few more weeks 2 go but- wow!!!: ) #soreadyallready!"

It's worth noting -- March 27 is Mariah's birthday, not her anniversary -- but for reasons that defy explanation, she has taken to calling her "birthday" her "anniversary."
