Bad Boy records honcho Sean “P. Diddy” Combs, 31, is keeping mum on the subject of recently released (from prison, where he served five years on charges stemming from a 1992 assault) Death Row Records founder Marion “Suge” Knight, 36, and the supposition that an East Coast-West Coast rap rivalry is due to flare up. Combs reportedly represents the New York contingent, while Knight is headquartered in L.A. The two reputedly feuded, as did their respective artists, Tupac Shakur and The Notorious B.I.G., before both rappers were shot to death in the late ’90s. “If y’all want to know ’bout East Coast-West Coast, why don’t you ask ‘Suge’ Knight?” Combs responded as he prepared to walk out of an interview with Details magazine for its September issue. “Why don’t you go interview him?” Continuing the thought, Combs is quoted as saying, “Time is money to me. And you wasting my time.” Beyond that, Combs in the magazine appears to be fearless when it comes to the naked truth. He and his new girlfriend, model Emma Heming, are displayed in a provocative photo layout in which the two wear diamond crosses, Chanel sunglasses and not much else.
