Kelly Clarkson, Fantasia, Carrie Underwood lead Simon Cowell tribute - Video

Kelly Clarkson, Fantasia Barrino, Carrie Underwood lead Simon Cowell tribute at the American Idol Finale. Former winners Ruben Studdard, Kris Allen, Jordin Sparks and Taylor Hicks were also there.

Later they were joined by former Idol contestants like David Archuleta, Jason Castro, Bo Bice, Blake Lewis and others -- all in white!

Notably absent were David Cook who was in a charity even and couldn't come -- and Adam Lambert who has publicly tweeted that American Idol did not invite him to this historic occasion! Why wouldn't FOX want him there when they had him as a mentor. Something fishy is going on.
