Kevin Spacey got dirty with Jimmy Fallon Friday on 'The Tonight Show.'

The 'House of Cards' actor joined Fallon's barbershop quartet, the 'Ragtime Gals,' in singing Jason Derulo's hit single, 'Talk Dirty to Me.' Spacey kicked off the first verse with impressive vocals sometimes heard from Frank Underwood on the television drama. Fallon followed and showed he, too, can carry a tune.

Who knew the words, "your booty don't need explaining," sounded so good in a five-part harmony?
