They do. But last night was the "finale" because it was their last performance.
I don't get the looks in the pic. She wasn't flawless, but she sang that cheesy ass song pretty well. Heck of a lot better than Blake. Seriosuly, Blake doesn't have a very good voice at all. Did he hit any of the high notes in that Maroon 5 song? And that's supposed to be "his" genre.
Horrible finale, though. Boring. There was one good point...
They didn't bring out the gospel choir for the final song!!!
ETA: Don't get me wrong, I luvs me a good gospel choir, but I've always thought it was really dumb to use in all the Idol finales.
