Jordin Sparks has been crowned as the newest and youngest American Idol.

The 17-year-old was announced as the winner of the US television singing competition on Wednesday night.

She triumphed over beatboxer Blake Lewis, 25, after a performance that wowed the show’s judges and the viewers who gave her the majority of the record 74 million votes cast.

“Mom, Dad, I love you,” Jordin, the daughter of retired NFL football player Phillippi Sparks, said after hugging her competitor.

The contest came down to either the stronger singer, Jordin, or the better entertainer, Blake.

The teen delivered her songs simply and powerfully, while her rival’s flourishes included his sound-effects beatboxing and sharp dance moves.

The finale show in Los Angeles featured stars including Gwen Stefani, Smokey Robinson, Tony Bennett, Bette Midler and Green Day, who performed A Working Class Hero Is Something To Be.

The two-hour show opened with the two finalists duetting on the Beatles I Saw Her Standing There, followed by Gwen singing 4 In The Morning via satellite from Massachusetts.

Past Idol winners and this season’s contestants got attention, starting with first-season winner Kelly Clarkson performing her new single Never Again.

And Melinda Doolittle, arguably the best contestant to miss out on the finale, returned to impress the crowd.

For their final performances, both contestants sang This Is My Now, the tune picked by viewers in an online American Idol songwriting contest introduced this season, along with two other songs of their choice.
