Rihanna Marks #1 Album, Singles with Post-777

ROLLING SNAKE EYES: No, this pic was not snapped in the locker room at Barclays Center after the Brooklyn Nets beat the N.Y. Knicks, but backstage at Webster Hall to mark the completion of Def Jam/IDJ globe-trotting pop diva Rihanna’s whirlwind “777” tour for her seventh studio album, the chart-topping Unapologetic, and 12th #1 single, “Diamonds.” Pictured just before Chris Brown tweeted he was on his way and an Australian journalist streaked the proceedings, are (l-r) Roc Nation’s Jay Brown, IDJMG President/COO Steve Bartels, Def Jam’s Tyran Smith, RiRi, Jay-Z and the singer’s grandfather.
