Diddy and T.I. hosted an after-party this past Saturday after the 2011 BET Hip-Hop Awards in Atlanta, and all was going well ... until ...  Well, until Diddy noticed a few of the partygoers were drinking Grey Goose instead of the vodka he endorses -- Ciroc.  That's about the time that all hell broke loose.  Your boy went on a bit of a rampage, and had some choice words for one club in particular.ATTENTION: PARENTS USE DISCRETION THIS VIDEO CONTAINS EXPLICIT LANGUAGE.

Feeling ashamed, Diddy took to his twitter and said:

"I'm a child of God and I should be better no matter what someone says to me.  I'm sorry for the ignorant way I represented myself and us, I have backslid and regressed.  Forgive me for my ignorance.  Pray for me pls.  I know better and I am better."

I have a responsibility that I promise I will live up to and I'm more disappointed in myself than you know.  I will humble myself and learn.....  Bottom line is I'm sorry to all!  Pls find it in your heart to accept my apology.  I will do better and be greater and a source of positivity!"

Speaking of Diddy, a former LAPD detective, who once worked the murders of Tupac and Biggie, has just released a book called "Murder Rap."  In the book, the former detective claims Diddy is responsible for Pac's death.

And speaking of Pac, a sex tape featuring the late rapper has recently surfaced and at least two porn company's are going head-to-head to buy the rights for it.
