Last week, Rihanna revealed via Twitter that her forthcoming 'Talk That Talk' album, due out Nov. 21, would feature just one guest artist.

"And we got the best!!!!!" she wrote, fueling speculation over the identity of said collaborator.

Now, the mystery has been solved. In an interview with the Norwegian website 730.no, Erik Hermansen, one-half of the production duo Stargate, has revealed that none other than Jay-Z, RiRi's onetime mentor, will appear on the record.

According to Hermansen, Hova raps on the title track, a "mid-tempo banger with hard drums, dirty synths, and Rihanna and Jay at their best." The song is the latest in a string of team-ups between the Brooklyn hip-hop mogul and Bajan pop superstar.

"This is the first time we do a song with Jay-Z and Rihanna together," Hermansen said. "Actually it's the first time Jay does anything on our beats."

"It was about time," he added.

Several days ago the 23-year-old Bajan songstress debuted the tracklisting for 15 songs set to appear on the effort.
