In the superstar vlogger’s latest video, she is driving a car whilst addressing the camera.
According to a source from the Metropolitan Police, Zoella ‘could have killed someone’ by driving during the filming of the short clip.
The told a UK magazine: "She could have killed someone. How can anyone who has their eyes off the road for that amount of time be in complete control of a vehicle?
"It's clearly a main road with plenty of people about. Anyone could have run out in the middle of the road and she wouldn't have seen them or had enough time to stop. This is completely irresponsible behaviour.”
A spokesperson for the YouTube sensation told The Mirror: “Zoe is an extremely careful and conscientious driver. At the time of filming she was in mostly stationary traffic. She takes road safety very seriously and would never do anything deliberately to counteract this."
Zoella has come under a wave of criticism following the revelation that her best-selling debut novel Girl Online was penned by a ghostwriter.
This doesn’t appear to have affected her YouTube pulling power as she continues to draw millions of viewers to her popular video channel.
