He also blasts those he believes were responsible for shooting him during a studio session in New York in 1994.
TRAGIC rapper Tupac Shakur targeted rivals including Dr Dre and P Diddy in a brutal letter written on the eve of his murder.
Tupac mocked fellow rappers like Jay-Z, The Notorious BIG, Nas, and Mobb Deep before turning his guns on those he really had it in for.
In the handwritten letter, he labels rap megastar Dr Dre a “closet h**o” and accuses Puffy Daddy – now P Diddy – of plotting his downfall.
A heavily edited version of the note was used inside the album but the original – obtained by the US auction house Gotta Have Rock & Roll – reveals the true extent of his hatred.
In it Tupac also blasts those he believes were responsible for shooting him during a studio session in Manhattan on November 30, 1994.
He was shot five times and robbed of £30,000 worth of jewellery in the attack – which has been blamed for helping fuel the violent rap wars wars plagued the 1990s.
Tupac had been invited to the studio by James ‘Jimmy Henchman’ Rosemond in order to record a song with rapper Shawn ‘Little Shawn’ Wilkins.
He was accompanied by Randy ‘Stretch’ Walker – who was shot twice in the abdomen in the notorious ambush.
Though he was never charged, Walter ‘King Tut’ Johnson was named as a person of interest by law enforcement in connection with Shakur’s robbery.
According to investigators, Johnson admitted to a confidential informant that he shot Shakur in order “to discipline him”.
Johnson was eventually convicted of three armed robberies – not connected to the Tupac case -and became the first New York resident sentenced to life under the three-strikes law.
“I dedicate this 2 Jack ‘the snitch’ Agnant for ordering the hit, 2 Tut for shootin me, 2 Puffy, Big, Stretch, Lil Shawn, Jimmy Henchman & whoever else remained silent while conspiring my downfall,” Tupac wrote.
In other parts of the piece, Tupac targets Biggie Smalls’ wife Faith Evans and dubs De La Soul “fat washed up bums.”
On the night of September 7, 1996, Tupac was gunned down in a drive-by shooting in Las Vegas as he headed to a gig at Club 662.
Death Row Records boss Suge Knight was driving the car and 2Pac was a front seat passenger as they led a convoy of cars.
Former Los Angeles Police Detective Greg Kading claims Diddy was “linked to the Las Vegas drive-by killing” of Tupac which happened just six months before Biggie’s death.
It’s an unfounded claim the superstar has always vehemently denied.
