That's because Zoella, real name Zoe Sugg, has beaten the likes of Harry Potter author J.K Rowling to record debut book sales...selling over 78,000 copies of her debut novel 'Girl Online' in just a week.

The sales record is the highest since Nielsen BookScan began collecting information back in 1998, according to reports, and the book is the highest selling hardback of 2014.

Zoella has had a sensational year - she's gone from producing make-up tutorials in her bedroom to winning the Radio 1 Teen Award for best British vlogger, and sang on the Band Aid 2014 single raising money for the Ebola crisis in West Africa. 

\The star tweeted she had been "legit blown away by this" adding: "I never in a million years thought that so many of you would pick up a copy of Girl Online. Almost wanna cry..". Not surprisingly, the tweet has been favourited over 12,000 times.

Oh, and fans please don't worry - Zoella has signed a two book deal with Penguin (meaning another one is on the way!!)
