'American Idol' Finale Winner: Jennifer Lopez and Marc Anthony
Relegated all season long to being the supportive husband in the audience (and occasional technical assistant to the "Idol" Finalists), Marc Anthony came out and did a terrific rendition of "Aguanile" and got an extra assist when Jennifer Lopez came out and resurrected her Inner Fly Girl with some of the night's sexiest dancing. Any night where Jennifer Lopez gets to look beautiful, dance impressively and nobody asks her to sing is a good night.
