Fans of “The Masked Singer” were in for a shock!

Usually, fans are able to guess certain celebrities by their voices.

People knew the trio performing last season was Hanson by their distinctive voice.

However, they were never going to guess the voice behind the Hydra!

The duo (who could have been a trio) sang ZZ Top’s “Sharp Dressed Man” for their final performance.

Only guest judge Nicole Byer provided a correct guess of magicians Penn and Teller!

Teller doesn’t usually speak in his acts so no one was able to recognize his voice.

Penn revealed that Teller did two of the voices since his own voice was so recognizable.

Fans can’t wait to see who will be unmasked next week!
