OK! Exclusive: Nicole Not Working With Rihanna

Although a new story had Nicole Richie stepping into the singing spotlight to collaborate with sultry songstress Rihanna, a rep for the star insists that just isn't true.

"While Nicole respects Rihanna and thinks she is immensely talented, she is not currently working on an album and hence, not currently working with Rihanna as has been recently reported," Nicole's rep tells OK!.

As relayed by the New York Daily News' Gatecrasher column, Nicole was supposedly hooking up with "pals" Rihanna and Kelly Osbourne in preparation for a new album.
