'Lucky Day' songstress Nicola Roberts has revealed that she's not sure if she wants to tour as a solo artist or not yet. 

Speaking exclusively to the Daily Star newspaper, she explained that she wants to "wait to see if people care" about her music enough to warrant a string of live dates and the thought of performing alone makes her nervous:

"People have to want me to tour. I’m a realist. I need to wait to see if people care first. If the demand is there, I’d love to tour. But playing live on my own is scary."

"My first solo show was a festival in Newcastle to 10,000 people and I felt so alone on stage. I was aware of all this space behind me where the other girls would usually be, and I thought: ‘Wow, this is a whole new ball-game.’”
