Jessie J and The Roots Perform 'Masterpiece' on 'Tonight Show'...

Assisted by The Roots, a warbling Jessie J took to the stage on last night's 'Tonight Show Starring Jimmy Fallon' to perform her empowering anthem 'Masterpiece' off her latest album 'Sweet Talker.' 

She's a talented vocalist, but sometimes her singing technique annoys me. The track will see a release on March 23rd. Peep the performance below.
