The wait may soon be over for Rihanna's first official single to be released since 2008.

Deemed to preceed an album release date reported by Play.com of November 23, sources claim the as-yet-untitled single could premiere "any day now".

While the news has not be substantiated by Rihanna's team or label home, singer/songwriter Ne-Yo says fans should expect a "never heard before" Rihanna when the music debuts.

"Expect an edgier, almost angrier Rihanna on this one. Rihanna says some things on this album that you've never heard her say before," says Ne-Yo.

While the prospect of an angrier and edgier Rihannaa looks promising, in terms of creativity, Ne-Yo hopes she'll lighten up on a few songs.

"I'm not supposed to say anything but I'm going to work on as many songs as possible with her. I'm going to lighten her up. I don't want an angry Rihanna."

Rihanna's last single, titled "Rehab" was released in October of 2008. She has since been heard on Jay-Z's Billboard Hot 100 Top 5 charting single "Run This Town" alongside Kanye West.
