Pia Toscano may be off “American Idol,” but she’s not about to be bounced from the music biz.

The 22-year-old La Guardia HS of the Performing Arts grad from Queens was all smiles yesterday as she traipsed in sky-high heels and a bright-red dress into the LA offices of Warner Bros. Records.

Meanwhile, fans Tom Hanks, Bette Midler, ex-“AI” judge Ellen DeGeneres and ex-contestants Jennifer Hudson and Chris Daughtry tweeted their outrage over Thursday’s elimination.

“How could the USA vote Pia off?” Hanks spewed. “I may be done for the season!”

Added Midler: “They dumped Pia!! How did that happen??”
