After sitting at #2 for weeks, Rihanna's latest single "S&M" has offically gone to #1 on the Billboard Hot 100, giving the singer her 10th #1 singer, thanks to Britney being on the remix. This also gives Britney Spears her 5th #1 single.
The original and the remixed version sold 293,000 copies last week, in result it ended Katy Perry and Kanye West‘s three-week reign with "E.T". Congrats to Rihanna and Britney.
