Mariah Carey’s Cleavage Is Bringing Sexy Back Home For The Holidays (PHOTO)

Mariah Carey is one high note away from a holiday wardrobe malfunction!

Honestly, what would the holiday season be without Mariah Carey? It’s just NOT Christmas/Hanukkah/Kwanzaa/Festivus without listening to “All I Want For Christmas Is You” on repeat, followed by multiple viewings of “Love Actually” and “A Christmas Story.” Or whatever your favorite holiday movie is. The point is, Mariah is a key ingredient in our holiday cocktails, and she totally knows it. Could this be why she was practically BURSTING with holiday cheer at the 80th Annual Rockefeller Center Christmas Tree Lighting ceremony last night? And by “bursting,” we mean her CLEAVAGE.

Singing such time-honored tracks as “All I Want For Christmas Is You” and “Christmas Time Is In The Air Again,” Mariah joined fellow performers Cee Lo Green and Rod Stewart in celebrating NYC’s iconic Christmas tree. In addition to killing it onstage, Mariah looked positively boobalicious as she posed with Santa (major props for not sneaking a glance, dude). We love that she’s looking so flawlessly festive, but Mariah, babe, please just remember to cover it up when you, say, sit down with the (Nick) Cannon family at Christmas dinner! We hear turtlenecks are coming back…
