The Roncalli guidance counselor placed on administrative leave for her same-sex marriage will be on The Ellen Show this week.

Shelly Fitzgerald is listed as a guest on this Friday's show, where pop superstar Cher will also appear and perform. According to the show's website, host Ellen DeGeneres invited Fitzgerald to share her story.

Fitzgerald's lawyer, David Page, confirmed the appearance in an email Monday afternoon.

Fitzgerald was a guidance counselor at the Catholic high school in Indianapolis for 15 years, before she was placed on administrative leave last month. Fitzgerald, who married a woman in 2014, said she was told she could dissolve her marriage or lose her job.

In a statement posted to the Roncalli High School Facebook page weeks ago, officials said all employees must support the teachings of the Catholic church both in and out of school. That includes the belief that marriage is “between a man and a woman.”

The school said that expectation is defined in employee contracts and job descriptions so every employee can make an informed decision before the start of each year.

The incident has caused a rift at the school, which is under the auspices of the Archdiocese of Indianapolis. Many students, alumni and parents have called on the school to change the policy and reinstate Fitzgerald.

Last week, though, school administrators cracked down on some shows of support. Posters with a rainbow graphic and an invitation to celebrate Pride Day at Friday's football game were removed from lockers throughout the school. Principal Chuck Weisenbach said students were free to show support for Fitzgerald, but not for political causes.

"Since the start of Ms. Fitzgerald being placed on paid administrative leave, we have given students, teachers and staff leeway to show their support for her. Students continue to be allowed to wear rainbow attire and accessories in our school and to sporting events," he said in an email. "We believe there is a delicate balance between showing support for a staff member and advocating for a specific cause or political position."

Weisenbach said the posters were removed but students may continue to wear shows of support for Fitzgerald.

DeGeneres is a well-known LGBT activist. When she came out in 1997 while starring in the sitcom Ellen, she became the first openly lesbian actress to play an openly lesbian character on television. She has been married to actress Portia de Rossi since 2008.
