Dem Babies are certified showstoppers!

Looking glamorous in a sparkling white dress, Mariah Carey made her New Year’s Day concert a family affair by bringing her twins, Monroe and Moroccan Cannon, and hubby Nick on stage during a performance in Australia’s Gold Coast.

“Ms. Monroe greets the audience in Australia.. Thank u 4 coming!!” she shared on Twitter, posting a snapshot of the twins on stage.

The night before, Carey and Cannon got into party mode as they celebrated the arrival of 2013.

“Happy new year from Australia!!!!” the American Idol judge wrote.

After spending Christmas in Aspen, Colo., the family jetted Down Under, where they toured the Great Barrier Reef and explored the open waters on a spacious yacht.

The singer will wrap up her Australian tour with a final performance on Jan. 5.

All is merry and bright for Mariah Carey.

With Christmas only four days away, the American Idol judge got a head start on the festivities with hubby Nick Cannon and their adorable twins, Monroe and Moroccan, 20 months — and gave fans a sneak peek into their cozy celebrations on Twitter.

The family jetted away to Aspen, Colo., retreating to a getaway tucked away in the snowy mountains. “So beautiful! Christmas begins for me today. God Bless!!!!,” she tweeted.

And Cannon has caught the holiday spirit as well: Carey shared a photo of her husband dancing around their home, donning headphones (listening to “All I Want For Christmas (Is You),” perhaps?) and a pair of fuzzy lamb slippers.

After catching up on family time, the pop star engaged in a little retail therapy with a trip to a Gucci store and a jewelry shop in the legendary ski town’s shopping district. Happy Holidays, indeed!

Season 12 of American Idol premieres Weds., Jan. 16 at 8 PM on Fox — with Carey as one of its new judges.

Taking a break from her busy American Idol schedule, Mariah Carey tweeted a sweet snapshot of her daughter Monroe, 2o months, decked out in all-pink pajamas.  Topping off her festive ensemble: a matching pink bow, pacifier and strings of pearls.

“Ms Monroe seems to think sometimes pearls can be your best friends too: ),” Carey wrote alongside the photo.

As she raided her mom’s closet for a game of dress-up, little Monroe has certainly lived up to her girly demeanor. “She’s very dainty and she holds her own bottle. She’s Miss Independent, definitely Miss Independent,” Carey revealed during a Dec. 2011 interview.
