I do believe Dre is Gay. Tupac was close to him and he mentioned it on several of his songs (you're fruity as this alizee

) and his former boss Suge Knight also mentioned it in an interview. Of course he wants to keep that shit behind closed doors because it doesn't really fit his hardcore image (although people that know Dre well know that he never was hardcore - before NWA he was a preppy DJ with music so lame you couldn't imagine...
As for Eminem, he's just fucking big right now, that's why all the press. Tupacs movies were big too at the time, Ice Cube is just not big enough to get the same press. Although I do think he's a great actor (Boyz N The Hood, Tress Pass (also with Ice T), Friday)
Anyway, where did you catch Eminem TDF?
