Looks like Donny Osmond has never had to wash out his mouth with soap.

The 70s-era teen idol is known for being wholesome, so it came as little surprise when he told People magazine he cant remember ever using an expletive out loud.

Never. Because I never heard my father curse, he revealed in an interview out Saturday. He was tough, but he never swore.

Osmond said hes not completely curse-free, however.

Obviously I still think the words! he laughed. There are certain people I would love to say certain words to at certain times, but I just think, Be like your dad.

The Puppy Love singer earned a squeaky clean reputation after making it big with his brothers in the band The Osmonds, before embarking on a solo career, and then hosting the hit variety show Donny & Marie with sister Marie Osmond.
