Rihanna has added another milestone to her wildly successful career. According to Nielsen SoundScan, her latest release, Unapologetic, has cleared one million units thus far. This of course gives Rihanna another platinum plaque, making it her sixth album to sell over one million copies. This album has thus far sold at a faster clip than her previous album, Talk That Talk; it took that album sixteen additional weeks to reach platinum certification.

Meanwhile, the singer continues to push forward, as she remains on the road for her Diamonds World Tour. Her most recent single off the album, "Right Now," is starting to creep up on the charts; should it take off, it would become her fifth charting single off Unapologetic.
