As the host of American Idol, On Air with Ryan Seacrest, the American Top 40 and 18 other jobs dealing with the music industry, we've always wondered if Ryan Seacrest can sing.  Well, on Halloween he gave Jimmy Fallon a little taste with his version of "R. Kelly's Ignition Remix," and now we finally know whether or not Ryan can really sing.

I love Jimmy Fallon...putting Ryan Seacrest on the spot as the Roots back up his solo.
