The 25-year-old 'Who You Are' hitmaker recently released the new track 'Wild' from her upcoming album and she doesn't feel confident this time around, reported Daily Mirror.
Her new single features Dizzee Rascal and Big Sean. Her debut record 'Who You Are' has sold more than 1.2 million copies when it was released in February 2011.
"It is no different, it feels exactly the same, I don't ever expect anything so I've taken nearly a year out of releasing music.
"I'm not sleeping but in a good way, I'm excited, I want to know what people think, I want to know where it's charting in different countries. It's such a different sound this album and Wild is a very small reflection of what the album sounds like. It's exciting for me for people to hear the next single and the single after that because I know what they are now, it's exciting times," she added.
