Detox may still not have a release date, but that’s not stopping Dr. Dre from pumping out the singles. The hip-hop icon is prepping a second collaboration with Eminem for his long-delayed album. In a surprise announcement at the end of Showtime’s “Fight Camp 360°: Pacquiao vs. Mosley,” the narrator says that Dre will premiere his new Em-assisted single “Die Hard” during the show on Friday, May 6, at 10 p.m. This follows Dre’s previous collaboration with Eminem “I Need a Doctor,” which currently sits at No. 16 on the Billboard Hot 100.
