She's been working hard on her soon-to-be-released fourth studio album, and earlier today Rihanna gave fans a taste of her new single "Russian Roulette."

The "Take a Bow" songstress paid a visit to Ryan Seacrest's KIIS FM radio show this morning and finally broke her musical silence.

"Russian Roulette" was written and produced by Ne-Yo, who Ri-Ri collaborated with on "Unfaithful" back in 2006.

Rihanna's new album Rated R is scheduled to hit stores and online retailers on November 23rd, just over a month from now.
