Rihanna is gearing up to release her fourth solo album 'Rated R' -- the first project since the Feb. 8 assault at the hands of ex-boyfriend Chris Brown. The R&B diva, who recently compared herself to Britney Spears given the media-fare surrounding the assault incident, has decided to preview the highly-anticipated material for fans in London on Nov. 16 at a secret location.

The free gig will be streamed live online by Nokia and will mark the first official performance of her new music. "It makes me nervous," Rihanna admitted on Nokia's music blog, "because it's not just the 6,000 people in the venue, but it's millions of people across the world watching it all at once ... It's exciting though; it's a big thing that everyone can see it. There's no better way to launch an album."

In related news, a portion of Rihanna's interview with Diane Sawyer aired on 'Good Morning America' Thursday morning (Nov. 6) with the full interview airing later tonight on ABC's '20/20.' Rihanna describes the assault In the emotional interview as "humiliating" and admits to going back to Brown after the incident."I stayed. I even went back after he beat me, which was wrong," she admitted. "But again ... I'm a human being, and people put me on a very unrealistic pedestal. And all these expectations, I'm not perfect. Also it's pretty natural for that to be the first reaction. It's completely normal to go back. You start lying to yourself. The minute the physical wounds go away you want this thing to go away. This is a memory you don't want to have ever again."

'Rated R' hit stores and online retailers on Nov. 23.
