via MSN, 'A prison letter written by Tupac Shakur is up for auction and is likely to fetch over $100,000. But it’s the subject matter that’s gotten everyone’s attention.
In the letter to Madonna, Tupac admitted that he ended their relationship because she’s white.'
Tupac writes, "For you to be seen with a black man wouldn't in any way jeopardize your career, if anything it would make you seem that much more open and exciting."
The legend then confesses, "But for me at least in my previous perception I felt due to my 'image' I would be letting down half of the people who made me what I thought I was." It's an amazing letter. Tupac clearly knows he devastated Madonna by the rejection, saying, "I never meant to hurt you."
