Her Wikipedia page says she did work experience in Heat and Internship at Bliss and worked at Recognise Magazine?
her website says this:
I’ve had many jobs, from being the ‘bucket girl’ in my local florist (slimy flowers really stink) to writing book reviews for Heat magazine (seeing as I’m an avid reader this was my dream job). In 2011, after an inspiring chat with Dorothy Koomson, I decided to start writing my own fiction. A year later I signed a book deal with Penguin and then, in 2013, Billy and Me was published.
