Sometimes Mariah Carey behaves like she's 14 years old. And sometimes she behaves inappropriately with 17-year-old pop stars who look like they're 14 years old. (Sorry, Justin Bieber, just facing facts here.) If you're so inclined, check out the new music video for our favorite holiday song, re-mixed with the vocal stylings of Bieber and Carey as "Stacy's Mom"-in-Santa drag.
(All we want for Christmas is to un-see those images of Bieber A) doing that weird dance with his arms and B) cackling flirtatiously in a sleigh with a woman who could be his mother.)
