Rihanna hits a major milestone as her smash hit single Work ft Drake spends its 7th week at no.1...
Rihanna is now one of only two artists who have led the Billboard Hot 100 chart for seven weeks four times.
RiRi's first seven week streak started with 'Umbrella,' followed by her duet with Eminem 'Love the Way You Lie,' rounded out by her 10 week chart topper 'We Found Love.'
The only other artist to manage to stay on top for seven weeks four different times is Mariah Carey.
