Posted April 20, 201114 yr http://gossip.whyfame.com/files/2011/04/rihanna_britney_spears.jpg Now listed as featured artist on "S&M," Spears earns her fifth Hot 100 No. 1 and second this year, following her own "Hold It Against Me" in January. She had previously reigned with her debut single "...Baby One More Time" in 1999 and returned to the summit with "Womanizer" (2008) and "3" (2009). Source : Billboard ALSO: Rihanna made Billboard history as the first artist ever to have a lead single go #1 after her 2nd single ("What's My Name?" ft. Drake") went #1 on the Hot 100. Now, with "S&M" sitting atop the national audience chart with over 150 million in audience, and her powerhouse "S&M Remix," featuring Britney Spears rocketing to the top of the iTunes chart, Rihanna has done it again: her 10th #1 hit. "Rihanna's tenth #1 single is a monumental accomplishment and a testament to her incredible artistry," said Steve Bartels, President and COO of the Island Def Jam Music Group. "This was a truly collaborative and creative effort, spearheaded by Rihanna's tireless work and aided in no small part by the incredible Britney Spears and her team. I am extremely proud of Rihanna, her ongoing dominance on the charts, and the entire IDJ team who worked so diligently to bring this one home." http://www.islanddef...3&artistID=7366 1.
