Rihanna has broken pal Katy Perry's record for the most number ones on America's Pop Songs radio airplay chart.

She becomes the first artist in the 20-year history of the countdown to land 10 chart-toppers, thanks to the success of her latest release, Stay, which rose a spot to the top on Monday (22Apr13).

Rihanna has managed the feat in less than seven years - her first number one on the chart was 2006's Sos.

Her other Pop Songs number ones include Take a Bow, Disturbia, S&M and We Found Love.
