The Masked Singer is a German reality singing competition television series that premiered on ProSieben on 27 June 2019.

Hosted by Matthias Opdenhövel, the program employs panelists who guess the celebrities' identities by interpreting clues provided to them throughout each season.

Other panelists from previous seasons include Collien Ulmen-Fernandes, Max Giesinger, Bülent Ceylan, Sonja Zietlow, Álvaro Soler, Ruth Moschner and Rick Kavanian.

After further offshoots in Asia and the United States in January 2019, the show was announced in March 2019 to begin in Germany and made its debut in June 2019 on ProSieben.

In each live episode, celebrities such as singers, actors or athletes compete against each other in a singing competition anonymously in costumes.

In the second season, contestant Angelo Kelly left the competition voluntarily in episode 3 due to the COVID-19 pandemic.

In addition to the singing competition, hints to each masked singer's identity are offered during the show.

The show has an 'extreme security protocol' in effect both during and after filming to protect the celebrity's identities from leaking.

Everyone involved in the show signed a non-disclosure agreement which prevented anyone from revealing any information about the shooting dates, costumes or identities of the masks episode until its broadcast.

Due to the show's security, celebrities said they never encountered another masked participant on set, or if they did, could not speak to them.

The costumes worn by the celebrity contestants were designed by Marina Toybina, a four-time Emmy Award winner and by Alexandra Brander.
