Rihanna has made pop chart history in America after landing her 10th number one in just under five years.
Her S&M hit jumps up a spot on the new Billboard Hot 100, which will be released on Thursday (21Apr11), to claim the top spot, making her the solo artist to log the shortest span between a first and 10th number one in the chart's 52-year history.
It took her closest rival Mariah Carey five years and four months to land the feat; Rihanna did it in four years, 11 months and two weeks.
Only the Beatles and the Supremes have better chart records - the Fab Four landed their first 10 number ones in a one year, eight month span, while Diana Ross' Motown trio achieved the feat in two years, eight months.
The Umbrella hitmaker is only the ninth artist to total at least 10 Hot 100 number ones.
Rihanna's S&M displaces her pal Katy Perry's E.T. at the top of the countdown. Perry's track drops to two after spending three weeks at number one.
Another leading lady, Lady Gaga, scores the week's highest debut - Judas crashes into the Hot 100 at 10.
