Biggie apparently wanted Tupac to manage him when they were still cool.

Author Ben Westhoff recently did an interview with the “Murder Master Music Show” where he divulged details about the two rappers that he discovered for his up and coming book, Original Gangstas: The Untold Story of Dr. Dre, Easy-E, Ice Cube, Tupac Shakur, and the Birth of West Coast Rap.

“People forget that Tupac was already blowing up, already a pretty big star when Biggie was just kind of getting started,” he said. “Tupac kind of took Biggie under his wing and tried to teach him everything he knew, kind of took him to school. Biggie’s career wasn’t taking off as fast as he hoped it would, and so he actually asked Tupac if he would be his manager, and Tupac said, ‘No, I think you should stick with Puffy and he’ll get you where you need to be.’”

Their closeness is what eventually led to Tupac’s extreme hatred for the New York rapper, according to Westhoff. “After he got shot, Tupac believed that Biggie knew about it in advance, knew it was going to happen,” he said. “That made him doubly mad because he mentored Biggie so much and helped him, and he really believed that he double-crossed him.”
