The Barbadian singer has become the first female artist in history to achieve five number ones in consecutive years, starting with mammoth hit 'Umbrella' in 2007. The only other performer to have achieved this feat is the legendary Elvis Presley, who scored a number one in every year from 1957 to 1963.
Rihanna's success means that Matt Cardle dips to the runner-up spot this week with 'When We Collide', having successfully managed to hold his X Factor duet partner from the top of the chart for the last three weeks.
Katy B and Miss Dynamite yo-yo back from last week's 11 to their original position of four with 'Lights On', while Jessie J celebrates being named as the BBC's Sound Of 2011 by seeing her track 'Do It Like A Dude' rocket into the top ten for the first time, landing at five from 18.
Meanwhile, Rihanna continues her chart dominance as previous number one 'Only Girl (In The World)' and her David Guetta collaboration 'Who's That Chick?' hold steady at the back end of the top ten.
Looking beyond the upper section of the chart, Willow Smith's 'Whip My Hair' and Take That's 'The Flood' slip out of the top ten after losing four and seven places respectively to finish at 13 and 14.
The depths of the top 20, however, are this week home to three climbers in the form of 'The Flood' by Cheryl Cole, which is up 12 to 18, 'Raise Your Glass' by Pink, which rises from 21 to 19, and Alexis Jordan's 'Happiness', up four places to 20.
