It looks like Mariah Carey's 2-year-old daughter Monroe is following in her famous mama's footsteps — literally! When the pop diva returned home after pre-taping her performance for the annual Christmas in Rockefeller Center tree lighting ceremony (airing tonight, December 4 at 8 p.m. ET on NBC), she found her precocious little girl rummaging through mom's designer duds!

"Miss Monroe woke from her slumber only to snatch mommy's new  R.C.'s (Tré Chic) & prance around. Only 2 1/2, watch out," she posted on Instagram along with a picture of Monroe strutting her stuff in pink and white PJs and her signature pink specs.

Naturally, Mimi used this photo op to showcase how amazing she looks even when lounging — which she claims to love more than gussying up and going out, if you recall her episode of MTV's Cribs as well as we do. "I prefer to lounge," Mariah told the cameras while kicking back on a couch in the middle of her kitchen. "I have a rule against sitting up straight." Oh, Mimi.

Mariah and her hubby Nick Cannon welcomed their fraternal twins, Moroccan Scott and Monroe, on April 30, 2011, affectionately dubbing them "DemBabies." DemBabies not only make frequent appearances on Mariah's Instagram page, but they also have their own website. Because, obviously. And now that she's officially out for Season 13 of American Idol, the Grammy-winning singer will have plenty of time to bond with (and post pictures of) her adorable mini-mes.
