Jessie J Delivers Knock Out Performance of ‘Who You Are’ On ‘X Factor’

After her amazing performance of her Top 40 smash, 'Domino,' Jessie J made a return to the stage of 'X Factor' last week, this time appearing on her home turf in the U.K.

Dressed in a sexy black gown with a mesh front and plunging neckline, Jessie J's vocal performance of 'Who You Are' was about as dynamic as the special effects occurring behind her on the stage's backdrop. Her intense eyes matched the dramatic music as she locked her gaze into the camera on many moments, drawing that viewer at home right onto the stage with her.

Accompanying Jessie J on the stage with the house band was a variety of string players who sawed away on violins as smoke billowed from beneath them on the stage, adding an extra flare of presence to the emotion-filled and breathtaking performance.

'Who You Are' is the title track to the singer-songwriter's debut album that hit stores earlier this year. The red-hot album was quickly a fan favorite, as the disc charted at No. 2 on the U.K. albums chart shortly after its release.
