Coleen surprised by book success

Coleen Rooney has admitted that she was surprised by the success of her first book Welcome To My World.

The WAG said she was scared about writing an autobiography because it meant she was putting herself "on the line" for critics.

"I think writing a book - it's a big commitment," she told GMTV.

"You know, you're putting yourself on the line to get criticised and stuff, and when I first [did] it, I was just hoping that it [did] well and, you know, it got good reviews."

She continued: "But then when it went into the bestseller list - and it just kept creeping up and creeping up - and then one day I got the paper and it was number one, and it was just really good."

Rooney is currently promoting her second book Coleen's Real Style.
