The 'Bittersweet' singer admits she is curious about searching for herself on the internet but refuses to give in to her urge because she doesn't want to read anything negative.
She said: "As for forums and people dissecting stuff, I don't know. Those things can be kind of... It's not intended for me to view. So I think it would be unwise of me to look. People might be really positive but all you can remember is all the negative stuff. I try and steer clear on the whole.
"You know what it's like? You know when you're at school and you leave the room and you get the idea people are talking about you and you kind of want to know what they're saying. But it's best you don't. "
The 31-year-old pop star - who has two children, Sonny, five, and 14-month-old Kit Valentine, with The Feeling guitarist Richard Jones - thinks the web is bad for musicians because you can see criticisms instantly.
She explained to BANG Showbiz: "The internet has made everyone so self-centred. I don't think it's good for my head. You can check your Facebook and if you put a video on YouTube you can check that. And then you can check where your name is being discussed. It's not good to be so aware of all those things."
