Britney Spears confused her fans by speaking in a fake British accent whilst onstage during her concert at London’s O2 arena on Friday.
The 36-year-old was encouraging her fans to compete to see who could scream the loudest.
"Are you guys ready? Do you think you can do this?" she asked in her fake English accent. "One, two, three!"
"What the hell is wrong with you?" she told the other side. "You've got to do better than that. Let's try it again."
Britney famously spoke in a fake British accent during her now infamous run ins with the paparazzi back in 2007.
In 2008 the star’s ongoing mental health problems resulted in a hospitalisation and her father Jamie Spears obtaining a conservatorship over her – which is still currently in place.
