Rihanna has banned fans from bringing umbrellas to her gigs in a move based on security fears.

Security guard Andy McDonald told the newspaper: “We don’t normally ask people to leave an umbrella outside. But we were taking precautions over a potential accident.

“We were told that Rihanna’s song features dancing with umbrellas on stage. We didn’t want the crowd following her actions and someone getting their eye poked out.”
