It's the time of year when viral Christmas videos start hitting our screens like St. Nick sliding down chimneys. But we've got a special stocking stuff for Britney Spears' fans: A parody of "Slumber Party," featuring none other than Drag Race diva Derrick Barry.

"Christmas Party" is set in the world's worst office holiday get-together, with Barry joining the festivities and "gettin' drunk on box wine."

Director Adrian Anchondo said he's long wanted to work with Barry, whom he calls "a great dancer and singer with an amazing sense of humor." The idea for his video, though, went through something of an evolution.

"I originally had an idea and wrote lyrics to "Make Me Ooh"... about a cow who was in love with Old McDonald and singing "Make Me Moo" whenever she was being milked. Needless to say, this Christmas video was a much better idea," he jokes.
