American Idol contestant Jessica Sanchez received a standing ovation from the judges and audience with her rendition of Whitney Houston's 'I Will Always Love You,' which judge Randy Jackson called "one of the hardest songs in the world to sing."

The 16-year old's cover of the late singer's hit last night prompted judge Steven Tyler to say she "may be the one" that will become this year's winner.

"Just amazing. I don't even know what to say," Jennifer Lopez exclaimed.
