Vlogger Zoe Sugg, also known as Zoella, has signed a two book deal with Penguin Children's.

The first title Girl Online, a story about a 15 year old's relationship with an American pop star, is set for release in November this year. Sugg, who has 4.9 million YouTube subscribers, commented 'When I was around the age of 14 I had my mind set on the fact that I would one day write my own book, something that other people would love to read. I then started writing my blog in 2009 and would never have imagined it would bring me the opportunity to make my teenage dream come true'.
