Mimi plays second fiddle to no one, so of course she'd be the first to welcome 2013.

On Monday morning (for the U.S.), new American Idol judge Mariah Carey tweeted this photo of herself with husband Nick Cannon, writing, "Happy new year from Australia!!!!"

Mariah, Nick and dem babies, twins Monroe and Moroccan, have been vacationing in Australia before her weeklong concert tour.

According to E! News, they're ringing in 2013 on a luxury yacht anchored along the Great Barrier Reef. Must be nice!
