The Bajan singer becomes the first female solo artist to top the chart six times in five consecutive years, having previously held pole position with 'Umbrella', 'Take A Bow', 'Run This Town', 'Only Girl (In The World)' and 'What's My Name' between 2007 and January this year.
'We Found Love', which also features veteran producer Calvin Harris, sold over 87,000 copies within just four days of release. It serves as the lead track from Rihanna's upcoming sixth studio album Talk That Talk.
Rihanna's late arrival prevents Maroon 5 and Christina Aguilera from finally breaking through to the top spot, as 'Moves Like Jagger' settles for second-place for a sixth week in a row.
Outgoing number one 'Loca People' by Sak Noel drops down to third, One Direction gain a place with 'What Makes You Beautiful' at four and Goo Goo Dolls finish the top five with 'Iris', which leapt back to the single digits last Sunday after it was covered by X Factor finalist Frankie Cocozza.
A few spots behind are electric hip-hop duo LMFAO, who glide to seven from 20 with the week's highest climber 'Sexy And I Know It'.
Elsewhere, Pixie Lott crashes out of the Top 10 for the first time with 'All About Tonight', down five to 14, David Guetta and Usher team-up 'Without You' jumps to 15 from 18 and Rihanna celebrates a second appearance in the Top 20 on Nicki Minaj track 'Fly', which is up eight at 16.
Calvin Harris and Bruno Mars fall five apiece to 18 and 19 with 'Feel So Close' and 'Marry You', while the top 20 concludes with Charlene Soraia and her cover of The Calling classic 'Wherever You Will Go', a new entry this Sunday.
