 The song 's reign at number one in the United Kingdom occurred as the country was hit by extreme rainfall and flooding , which led the British national newspaper The Sun to humorously suggest the two events were related , with the media referring to it as the " Rihanna Curse . " The tabloid also highlighted the date of the single 's video shot which was Friday the 13th ( April 13 , 2007 ) , adding further coincidence of the curse . Before the single 's release on May 14 , the temperature in London was relatively high , reaching 20 ° C. However , just a day after the release , " severe weather warnings hit the headlines " . An article in The Sun urged readers to join the campaign to knock the song off the chart 's top spot , suggesting to readers several other songs to download instead , all of which shared the theme of sunshine or summer .
