Rapper Wiz Khalifa and his boo, Amber Rose, are gong to take their relationship to the next level -- the recording booth.

The lovely couple revealed that they are working on a unknown musical project together. "We're working on some music for me," the blond bombshell told Billboard while attending the MTV Video Music Awards. "It's going to be very mysterious. You may not even know it's me. We might just throw it out there, might give it out and see what's up."

Now will Amber spit a 16-bar rap on a song with Wizzy? Who knows? But with today's technology, anyone can be a rap star including a gorgeous model like Ms. Rose. It would be interesting to hear what she does with her fiance.

Wiz also revealed that he will be making a cameo in Rose's new film 'Gangs of Roses II: The Next Generation.' The movie is the sequel to the 2003 all-female western starring Lil' Kim, Bobby Brown, Lisa Raye and Stacy Dash. According to BET.com, Part II will feature Rose, Vivica A. Fox, Charlie Baltimore and The-Dream's ex-wife Christina Milian.

Outside of that, Wiz is simply enjoying the remainder of the summer. "I'm also working on another album and stuff like that," he adds. "Just chilling out, having fun, I just got done with touring."
