For years, “The Masked Singer” fans have wondered whether former contestants were eligible to compete again on the reality TV show. After all, they’d be hidden under extravagant costumes so no one would know whether it was a new celebrity or someone that had already been unmasked. During the November 3 episode, Jenny McCarthy seemed to confirm there was no rule prohibiting former singers from returning to the stage.

“It could also be someone that has been here before,” she told her co-panelists when trying to guess the identity of the Caterpillar. “There’s no rules to say no one can come back twice.” Robin Thicke, Ken Jeong and Nicole Scherzinger all agreed. Jenny then threw out Joey Fatone‘s name, aka the Rabbit from Season 1.
