The 25-year old continued: "I know I'm going to be like losing half a stone in weight overnight, so I'm going to have to get myself into the zone."
When asked about the stress of striking out on her own, away from comforts of Girls Aloud, Roberts explained: "There does feel like there is a little bit of extra pressure, coz it is just me and it feels a little bit like, is that enough, is it enough to just look at that."
Roberts stated: "I think we’re all proud of each other, I think that kind of is the beauty...you kind of step out of the bubble that we were in for so long and you are able to see each person really develop on their own, everyone is achieving different things which is really nice to see."
She added: "I just think for me, I like literally went from school to being in the band, so other than the make up range, I have never really had that much responsibility and I feel like it gave me a lot of confidence having that much responsibility writing the record. Creating the record has made me grow up and it has made me, really push myself, it’s been good."
