Miley Cyrus has officially ruined Christmas.

The controversial pop star shot a promo for UK's Love magazine. Of course, the holiday-themed video, with animated Christmas trees and reindeer antlers, wouldn't be complete without a touch of Miley. Aside from her signature tongue wagging, the 21-year-old brings her classic raunch. "Merry Christmas, love!" she yells before lifting up her seemingly demure dress to show off underwear with a penis doodle. At least she wasn't going commando.

It's safe to say she's on Santa's permanent naughty list.
