Dr. Dre, Eminem Preview "Die Hard" On "Fight Club" (VIDEO)

As promised, Dr. Dre previewed his new track "Die Hard," featuring Eminem, on Showtime's "Fight Camp 360°: Pacquiao vs. Mosley," which aired last night. The track is set to appear on his highly-anticipated "Detox" that fans have been waiting on for what feels like ions now (about seven years to be exact). "Die Hard" is reportedly not the next single off "Detox," but just an offering that seemed appropriate for last episode of this particular "Fight Club" series.

In related news, Manny Pacquiao and Sugar shane Mosley are set to go toe-to-toe in the ring tonight (May 7), and, as previously reported, Rick Ross will escort Pacquiao to the ring.
