Classy lady! Pop star Ke$ha partied in Hollywood last night with some gal pals, but before she was driven home, the singer gave an impromptu interview with our photogs...

The tables turned when Ke$ha popped the following question: "Who has the biggest d*ck of all y'all? Anyone wanna whip 'em out for me!"

Wow, is it possible to love her even more? And what did the paps say? Watch the vid to find out what happened!
