Lamar's angry letter, posted on Twitter, is a response to a published interview with Lamar's father, Joe Odom, in which he claimed the Kardashians cursed Lamar, ruined his career, and put so much pressure on him that he turned to drugs.
Joe also called Kris Jenner "an evil bitch."
Sources who have first-hand knowledge of Lamar's actions tell TMZ ... he did NOT send the tweet. In fact, they say he has no Internet where he's staying and he wants it that way.
Read the full letter after the cut...
Won't continue 2 speak on this but I have got 2 let this out real quick. I have let this man and many others get away with a lot of shit. He wasn't there 2 raise me.
He was absent ALL of my life due to his own demons. My mother and grandmother raised me. Queens raised me. For the first time since they left, came a blessing of a FAMILY that I married into. FAMILY. That man wasn't even invited to my wedding. He has never met my mother in law and some of my other family.
How can a man who has NOT once called me to check on my well being have the nerve to talk so recklessly about his own "son". He is my downfall! His own demons may be the ONLY thing he gave 2 me. He disrespecting the ONLY FAMILY that has loved me without expecting anything in return.
They are the ONLY ones that have been here consistently 4 me during this dark time. Only person 2 blame is myself. Say what you want about me but leave the ones who have done nothing but protect and love me out of this! This goes to out to everyone!
They claim Lamar doesn't even know about the comments his dad made -- and the tweet Lamar supposedly wrote in response is bogus.
