Jessie J performs ‘Burnin’ Up’ on ‘GMA’...

Jessie J may not be what you want to hear in the morning when you get out of bed, but home-girl SANG her ass off on 'Good Morning America’s' Fall Concert Series this morning! 

In promotion of her new album 'Sweet Talker' (due October 13th), Jessie warmed up the stage with her vocal acrobatics while performing new single 'Burnin' Up.'

Her VEVO also premiered an acoustic performance of 'Ain’t Been Done,' which can be watched below.
