Many believed the murders were part of a 'war' between top East and West Coast rappers - Diddy and Biggie were part of the East Coast, New York-based, rap scene while Shakur belonged to the West Coast, LA-based scene.
Ri-Ri was enjoying a night of fun with celebrity pal Rob Kardashian.
Rob, 25, is currently dating Rihanna mini-me Rita Ora but he is also good mates with her record label buddy.
So the pair donned helmets and raced round the Racer’s Edge track at full pelt.
Rob, on the other hand, wore a pair of brown chinos and a grey vest.
Apparently, the star is dating singer Rita Ora, who is very much compared to Rihanna most of the time.
Riri dominated Rob completely with her number 16 kart.The cheeky star, 24, raised the one-fingered salute on her way out of a go-karting track in California.Christopher Wallace, aka Biggie Smalls - a close friend of P Diddy - was shot dead six months later in a revenge killing, according to retired detective Greg Kading, who once led a special task force that investigated the shootings. Kading led the task force whose job it was to disprove the claims in the 0million wrongful death lawsuit brought against the LAPD police by Biggie's mother Voletta Wallace.But on the night of the fatal shooting, on September 7, 1996, it was actually Keffe's nephew Orlando 'Baby Lane' Anderson who shot the 25-year-old rapper dead, according to the ex-cop. Kading says that in retaliation for Tupac's death, his manager Marion Hugh 'Suge' Knight hired rival Blood gang member Wardell 'Poochie' Fouse to kill Diddy's long-time friend Biggie Smalls for just ,000. His team were able to find enough evidence to clear the LAPD and all its officers of any wrongdoing, and the investigation was all but dropped (pictured are boxes of evidence)Shortly afterwards, Tupac had been on the way to a night club, standing with his head out of the car's sunroof, when another vehicle pulled up alongside him and and unknown occupants shot him, hitting him in the chest, pelvis, right hand, thigh and lung.Above: Tupac and Suge are pictured together Kading claims that the rap mogul was behind the murder of Biggie - also known as The Notorious B. But another popular theory was that Biggie's death may have been the work of David Mack, a corrupt former LA police officer who served 14 years in jail for a 2,000 armed bank robbery in LA in 1997.
