Ryan Seacrest Singing -- You Are NOT the Next 'American Idol' [VIDEO]

Ryan Seacrest finally showed off his singing chops for the world to see ... and the world wishes he hadn't done that.

Seacrest, always on top of the latest musical trends, belted out the classic 1989 Richard Marx song "Right Here Waiting" ... and "American Idol" even unearthed Marx to sing it with him!

Say what you will about Ryan's singing -- and it was awful -- he didn't hide behind any audio gimmicks ... he straight up sang his heart out.

As the old saying goes -- those who can't ... host.
