Christina Aguilera celebrated her 28th birthday last night with a “Clockwork Orange” themed party.

Dressed just like the “droogies” of the movie, Christina was decked out in white, with black boots and bowler, and even carried a cane. To complete the look, she had appropriate make-up around one eye.

Husband Jordan Bratman was dressed the part too, as was guest Joel Madden, though Nicole Richie chose to avoid the costume route.

Sounds like Christina had a pretty good birthday bash!
