This might be the most amazing thing I've ever seen. Ever.

On last night's American Idol Finale, Caleb won, but that's not the biggest news of the night!

Host with the most, Ryan Seacrest, sang on National Television!

He did a very short, very awkward duet with his childhood idol, Richard Marx -

He looked so scared!  I can only imagine how nervous he was!  He was live, in front of millions of people, and surrounded by some of the country's biggest talent!

Even though I don't think he should quit his day job, I have to give him some credit!  Way to go Ryan!
