Stick to hosting, Ryan Seacrest! He surprised fans on the season 13 finale of "American Idol" by singing Richard Marx's "Right Here Waiting For You." He was even joined on stage by Marx himself!

"All season I've been trying to get our star quarterback, Mr. Ryan Seacrest, to sing a little something for us," Randy Jackson said. "And now, I've got his whole family on board with it!"

The KIIS-FM radio host's family was in the audience alongside Jackson.
