The singer, who has started work on the follow-up to her chart-topping debut Overcome, promised a "sexier" record that will take risks.
"It’s got to be sexy. So I’m going to get a lot fiercer and sexier," she told the Daily Star.
"We’re just getting down and dirty with the next album. I’m going to take a lot more risks and it’s going to be insane."
Asked if she had any big collaborations on the LP, she confessed: "I can’t say too much because my management will kill me if I let loose. But I have a special duet planned.
"I have the ideas, the collaborations in my mind - it’s all locked up in my head."
The 'All Night Long' star recently celebrated selling over four million records - a combined total of albums and singles from her debut album.
