Uhhhhhh. Oh, boy. Either People magazine got some really bad information on Christina Aguilera's Halloween costume this year, or Christina Aguilera herself doesn't know who or what Zelda is.
Either way, according to this issue of People—and caught by Gamervescent—depicted above (and in full below) is "game heroine Princess Zelda, and beau Matt Rutler suited up as her love interest Link." At least they got the gender/names right?
Interestingly, if you visit People online and check out a similar image, the description is somewhat different.
"The queen's got her knight in shining armor! Christina Aguilera poses with boyfriend Matthew Rutler," it reads. Guess someone figured it out.
