Rihanna has banned people from bringing umbrellas to gigs on her current UK tour, because she's concerned they might cause injuries. The singer's set includes a rendition of 'Umbrella', featuring dancing with actual umbrellas, and it's thought that accidents might occur if fans try to copy it.
Aberdeen Exhibition Centre Security guard Andy McDonald is quoted as saying: "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".
