'American Idol''s Breathtaking Finale Performances

By
Season 10 of "American Idol" went out with a bang. The finale was jam-packed with the "Idol"s performing with their own idols.
'Kung Fu Panda 2''s Jack Black jazzed things up with Casey Abrams, while winner Scotty McCreery got his country twang on with Tim McGraw. Other country sweethearts Lauren Alaina and former "Idol" champ Carrie Underwood teamed up their powerful voices.
Lady Gaga and Spiderman both took leaps of faith in their hair-raising performances. The air-borne superhero's high-flying act was without a hitch in the Nokia Theatre at L.A. Live. The always sensational Lady Gaga finished things off with a real cliffhanger, leaping off "The Edge" with her backup dancer.
Judge Jennifer Lopez shook her signature asset during husband Marc Anthony's performance. The happily married couple ended the performance with a passionate kiss. Fellow judge Steven Tyler took the stage solo, sans his band Aerosmith, to win over the packed crowd.
This is just a small sampling of the spotlighted guests in the finale that surpassed the two hour mark. Watch the video for snippets from these standout performances. "American Idol" returns to Fox in January.
