The US actress, who plays Sue Sylvester in the musical TV series, said she wants to go as the Mad Men character played by Jon Hamm during the holiday later this month.
Speaking to Access Hollywood, she said: 'I'm going as Don Draper from TV's Mad Men. I love Jon Hamm and I love his performance and I got this suit, I've got a silver tie and a white shirt and I'm gonna grease my hair back.'
Lynch, who recently won an Emmy for her role in the show, has hinted audiences may see her character Sue on an episode of SNL soon.
She said: 'I know they're working on a Glee something or other. I might be reprising Sue and I might not. I might be myself, we'll see.'
