Kevin, who plays Artie Abrams on the musical series, said he's excited about fans seeing the festive episode.
"We're doing a take on Love, Actually, the episode's called Glee, Actually and everybody has their own storyline," he explained from the red carpet at the Trevor Live event in Los Angeles.
"Mine, well, I'm very excited, it's something we've never ever done."
Kevin kept tight-lipped about what exactly his storyline would involve, but hinted that it was based on a famous Christmas story.
The episode will be directed by Adam Shankman, who adapted Rock Of Ages for the big screen earlier this year.
