The singer's sixth studio album returned to number one on the British tally on Sunday (August 12), despite being first released last November.
However, the collection only sold 9,578 copies to reach the summit, making it the UK's lowest-selling number one since modern records began, reports Music Week.
Not since Millward Brown began supplying data to the Official Charts Company in 1994 has a number one album sold so few copies.
The low sales also mean Rihanna has collected the title for the lowest-selling number one of the 21st Century.
Emeli Sandé's Our Version of Events previously held the position when it returned to the top of the chart with sales of 13,430 just 11 weeks ago.
During the 967 weeks for which Millward Brown has been supplying the OCC with album sales data, it is the first time the number one position has been claimed with sales of fewer than 10,000 units.
The previous low was The Cranberries' Everybody Else Is Doing It, So Why Can't We? with sales of 11,981, 947 weeks ago.
