Watch Jessie J Rap Nicki Minaj's 'Bang Bang' Verse
Sure, Jessie J can sing with her mouth closed, but can she rap?
She knocked off covers of the first two artists without trouble, but hesitated before taking on her co-performer's "Bang Bang" part, stating she hadn't done it before but noting Ariana Grande had (according to Jessie, Grande was quite good).
Luckily, she didn't have anything to worry about (except an unfortunately placed microphone). Take it away, Jessie.
