Carol Burnett is set to guest star on "Glee" on an episode that airs on Tuesday, playing cheerleading coach Sue Sylvester's retired Nazi hunter mother, Doris.

Jane Lynch, who plays Sylvester, the show's villain, had confirmed the 77-year-old veteran television actress' appearance to OnTheRedCarpet.com in August.

Burnett, an Emmy winner who had her own sketch comedy series between 1967 and 1978, has in recent made several guest appearances on contemporary shows such as "Desperate Housewives" and "Law & Order: Special Victims Unit."

Burnett told the Des Moines Register newspaper in early November that she began watching "Glee", FOX's hit musical sitcom that depicts the lives of high school misfits and popular kids in a glee club, last year.

"Sometimes things come to me, and I'll read them and think, 'OK, would this be fun to do?'" she said. "And if the answer is 'yes,' then I'll try to do it. But I'm not just out there wanting to work all the time. Really, I just like to have fun. I think I've earned it."

"Glee" has often featured major celebrities, such as singer Britney Spears, who had an entire episode dedicated to her music, and film actress Gwyneth Paltrow, who played a free-spirited substitute teacher on an episode that aired last week.
