The new video for the Mariah Carey/Justin Bieber collaboration 'All I Want For Christmas Is You' is raising more than a few eyebrows.

The clip, which you can watch below, features the 41-year-old Carey dressed in an uber-sexy Santa costume with nary a trace of the weight she gained while pregnant with twins, catching the eye of the 17-year-old tween sensation -- and then cuddling up with him at the end.

Baby, it is officially no longer cold inside. Yowza!

The song, a remake of Carey's ubiquitous 1994 holiday hit, is on Bieber's newly-released 'Under the Mistletoe' album, and in addition to the questionable May-December romance aspect of the video, there's also some rather shameless product placement for the Nintendo DS and for Macy's (both Carey and Bieber have appeared in commercials for the department store). But it wouldn't be the holidays without a little commercialism.

As creepy videos go, this one ranks fairly low -- but that hasn't stopped a lot of parents from sounding the alarm around the Web. Take a look below and decide for yourself.
