YouTube blogger Zoella has revealed she is temporarily quitting the internet amid controversy over her record-breaking debut novel.
Zoe Sugg's Girl Online, about a teenage blogger and her relationship with an American musician, sold 78,109 copies in its first week - the highest first-week sales since Nielsen BookScan began collecting data in 1998.
But allegations emerged that the book was ghostwritten, sparking intense scrutiny on social media.
Yesterday Zoella asked for patience from her fans awaiting a video blog about Christmas. She wrote on Twitter: "Bare with me on vlogmas. I'm taking a few days out and off the internet because it's clouding up my brain. Thanks for understanding."
The 24-year-old admitted at the weekend that she was given "help" writing the book but insisted the story and character were hers.
She said: "Everyone needs help when they try something new. The story and the characters of Girl Online are mine. I want to thank all of you who have taken time to support the book."
