We're not exactly sure what it is, but it definitely sounds huge. According to 50 Cent, he and Common have something major planned.

Word of a joint project of some sort came after the G-Unit boss bumped into the 'Resurrection' MC. Fif posted an Instagram photo of their encounter with his surprise announcement. "Ran into Common," 50 scribed. "We on the move. Big things to come."

It'll be interesting to see if their collaboration will come in the form of a song, a consumer product like headphones or perhaps the rappers-turned-actors will star in a film together.

Either way, some may be surprised these two are teaming up since they pretty much exist on the opposite sides of the hip-hop spectrum. However, there's no doubt their union will get loads of attention. Stay tuned.
