Of all the singing competition shows, none is more star-studded than “The Masked Singer.”
Once a singer is sent home, they are unmasked.
Donny Osmond placed second in Season 1 of “The Masked Singer” as The Peacock.

One member of the Osmond family who found out the secret without being told was his grandson Truman.
“And I felt so bad, because I couldn’t tell him.
He says, ‘Grandpa, I think it’s you,’ I said, ‘We’ll find out!

I don’t think so.'”
And the younger kids, they have no idea."
I get it because when I was doing ‘The Masked Singer,’ I couldn’t tell anyone."

Donny and Debbie Osmond have been married since 1978, and the couple have five sons and 14 grandchildren.
Especially the young ones [were like], ‘Wait a minute, is that grandpa out there?’
It was kind of interesting," he explained.
