Rihanna: Lil' Kim Collaboration?

Rihanna slips into a black PVC bodysuit with sexy cut-outs as she launches the North American leg of her Last Girl On Earth concert tour at GM Place on Sunday (July 4) in Vancouver, Canada.

The 22-year-old “Rockstar 101″ singer reportedly has a collaboration in the works with rapper Lil’ Kim.

“I’m a huge Rihanna fan,” she told Aussie’s Lifelounge. “And she’s a friend of mine, so if I had to guess, I’m 90% sure that song is probably in the works.”

Lil’ Kim continues, “I look at it this way: if it happens, it happens. And it should be a surprise. It shouldn’t be something that people are anticipating, or have their own personal opinions on it before it even comes out. So I probably won’t ever mention that again.”
