In the fourth episode of The Masked Singer, aired on Wednesday, October 7, 2026, on ProSieben and Joyn, two prominent undercover contestants were unmasked. The hit entertainment program featured a double elimination during its thirteenth season, revealing television personality Ruth Moschner and comedian Bastian Bielendorfer beneath elaborate disguises.
Operating under a new format for the current season, the competition features 16 distinct costumes divided across the initial rounds. In the fourth live show recorded in Cologne, four undercover stars performed before the studio audience and the judging panel cast their votes. The panel for this episode consisted of returning permanent members Verona Pooth and Chris Tall, alongside guest panelist Pietro Lombardi.

The Snowboarding Ape Revealed
The first celebrity to face elimination was the character known as “Three Sixty,” an athletic, snowboarding ape who performed a rendition of Lily Allen’s track “Hard Out Here.” Guest judge Pietro Lombardi expressed admiration for the performance, initially guessing that the singer might be Carolin Kebekus due to her vocal range and comedic background. However, Verona Pooth and Chris Tall quickly zeroed in on a different identity, correctly deducing that the performer was Ruth Moschner, a television host who previously served as a regular member of the show’s rating panel for multiple years.
Following the public and studio voting procedure, Moschner’s disguise was removed, confirming the panel’s accurate prediction. Reflecting on her participation, Moschner noted that performing under the heavy costume was exceptionally warm and physically demanding, though she described the experience as a full-circle moment given her history on the other side of the judges’ desk. Lombardi commended her accuracy, remarking that she had not sung a single false note during her appearance.
Party Mouse Groovy Unmasked
The towering performer immediately sparked debate among the panel. Lombardi recognized the distinctive voice and connected the contestant to a podcast hosted alongside Özcan Coşar, while Chris Tall correctly identified the comedian as Bastian Bielendorfer, known for the podcast “Bratwurst und Baklava.” Verona Pooth alternatively guessed Martin Schneider, and Chris Tall briefly considered Thomas Hermanns.
Despite the panel voting to advance “Groovy” to the next stage, the studio audience ultimately decided against saving the pink party mouse. Upon removing the mask, the nearly two-meter-tall Bielendorfer emerged, joking about the tight fit of the costume. The unmasking finalized the exits for the fourth installment of the competition, leaving eight remaining masked celebrities in the running for the thirteenth season.
