Isle Of Wight Festival Review: Jessie J Belts Out Her Best (PICTURES)

The voice of confident performer Jessie J filled the muddy fields of the Isle Of Wight Festival on Saturday as the raven-haired pop star took to the main stage for a crowd-pleasing performance.

Dressed in a laced black top that showed off her perfectly-toned stomach and a pair of faded jeans that were gaping from her thigh to her shins, the Price Tag singer wowed the mixed crowd of music fans with her impressive vocals and catchy tunes.

Most accustomed to working the stage with her dance moves, she told fans: "I can't stand still and I've never sung this song before or used a mic stand, but I'm just going to push myself," before showcasing her vocal talent with a rendition of Usher's emotional Climax.

It was enough to bring one girl to tears and the high-notes were pretty breathtaking, but the rest of the crowd were eager to hear the upbeat and feisty tunes she is better known for.

Sensing it was time to step it up a notch, she shouted "OK, now we can dance" and moved onto Luther Vandross's Never Too Much, which merged into her catchy album track Abracadabra - she was back to her swaggering and pouting self.

Screams rang out from the audience as she belted her touching ballad Who You Are, and by the end of the energetic set, she'd made some new fans, while pleasing her young loyal audience with festival-customised performances of her big hits Price Tag, Nobody's Perfect and Laserlight.

Proving she's better live than the radio, she bowed out with one of her sustained signature high notes - a long and loud Do-minoooo.
