The Masked Singer season 13 took a dramatic turn during its semi-finals episode on April 30, when Oscar-winning director Taika Waititi was unmasked as the season’s surprise character Lucky Duck.

The twist stunned viewers—and judge Rita Ora, who is Waititi’s wife.

Lucky Duck had been dropping clues throughout the season but fully entered the competition during the semi-finals, interrupting the elimination process and using the “Ding Dong Keep It On” bell to send  all four remaining contestants—Coral, Boogie Woogie, Pearl, and Mad Scientist Monster—to the finale.

Then came the shocker: Lucky Duck unmasked himself without prompting, revealing his identity to the judges. Waititi joked, “I’m a pop star, America!” and added that he joined the show just to see his wife. “You guys got her working so hard, I never get to see her,” he said playfully.

The semi-finals also featured standout performances, with Coral singing Billie Eilish’s “What Was I Made For?” and Boogie Woogie tackling Maroon 5’s “Maps.” Pearl delivered “You Don’t Own Me” while Mad Scientist Monster performed “A Bar Song (Tipsy)” by Shaboozey.

Season 13 has already unmasked stars like Edwin McCain, Erika Jayne, James Van Der Beek, Candace Cameron Bure, and Method Man. Hosted by Nick Cannon with judges Jenny McCarthy, Ken Jeong, Robin Thicke, and Rita Ora, the season finale airs May 7 at 8 p.m. on FOX.

Fans can expect even more surprises as the remaining contestants battle for the Golden Mask Trophy.
