Hip-hop star Kanye West's latest video could lead to viewers suffering seizures, experts have warned.
The promotional film for All Of The Lights features sexy singer Rihanna in a very revealing outfit.
Experts at Cambridge Research Systems found the video contains flashes at a rate high enough to trigger seizures.
"Rihanna has many fans in all age groups," said a spokesman. "We're concerned that this video could be dangerous for gentlemen of a certain age.
"Her frock in the film is very revealing and as she girates and dances bits of her keep flashing - bosoms, nipples, 'down there...'
"Nothing is left to the imagination and we fear that some gentlemen may be in serious danger if they watch."
