LOS ANGELES — There wasn't only one performance of Adele's "One and Only" on "American Idol."

Elise Testone, the soulful 28-year-old teacher from Charleston, and Jen Hirsh, the soaring 25-year-old singer from Agoura Hills, Calif., both tackled the same jazzy Adele tune during Wednesday's performances from the top 12 female semifinalists on the Fox singing contest — and both were lauded by the judges for their take on the Grammy darling.

Hirsh was the first to perform, compelling Randy Jackson to note that she was "one of the greatest singers in the competition this year." Testone was seated behind a piano when she closed the show with her rendition, prompting Jackson to repeat himself. He told Testone she has "one of the best voices in the competition."

"For me, you're one of the best singers, maybe the best singer here," Jennifer Lopez echoed to Testone.

The top 13 contestants will be name when the Fox show airs tonight at 8.
