Jessie J sings without a mic in Ain't Been Done acoustic

Pop star Jessie J has performed an acoustic version of her song 'Ain't Been Done'.
Accompanied by a guitarist, the singer shows of her vocal talents by rapping and singing without a microphone, reported Digital Spy.
'Ain't Been Done' is featured on the singer's third studio album Sweet Talker, which also features singles 'Bang Bang' and 'Burning Up'.
Jessie recently admitted that she was 'soft' on her 2013 sophomore album Alive.
When asked if she had to rein it in at all for Sweet Talker, the singer said she didn't and decided to "let go".
"But I definitely feel like I tried to soften myself on the second album and listening back to it now - I love the album, I think it's really good still - but I just don't think there's enough soul in it and I wanted to get that back," she added.

"It hasn't gone anywhere, I was just told to, you know, well, not told, but the feeling was that I should maybe try and sing a little softer.
