Steven Tyler predicts Jessica Sanchez will be new 'Idol' There's still one week to go before "American Idol's" 11th season finale, but Steven Tyler made a bold prediction Wednesday that 16-year-old standout Jessica Sanchez will clinch this year's title. Performing three numbers Wednesday, the teen from San Diego, Calif., tackled Mariah Carey's "My All" for the first judges' choice round. Jennifer Lopez -- who sources tell Us Weekly will bow out of Idol after this season's finale -- knew it was a tall order when choosing the song for Sanchez, and applauded her for pulling it off.

That's what we wanted to show people (with our song choice): that you could get through a song like that and do it in a beautiful way -- and you did. Longtime Sanchez supporter Tyler, 64, was especially wowed by her rendition -- and quickly declared it was game over for fellow finalists Phillip Phillips and Joshua Ledet. "When you sing you make people hang on your every note," the Aerosmith frontman said. I hope you get used to encores. You'll be the last one standing, I believe.

Ledet -- who impressed with his version of Mary J. Blige's "No More Drama" among other songs -- says there's no hard feelings when it comes to Tyler's endorsement of Sanchez.

I want to win, but at this point, we're all winners. I'm not gonna say I don't care, but I will be just as happy about me winning (as I would if) Phillip or Jessica win. Does Jessica Sanchez deserve to win "American Idol"?
