Did Dre rap with biggie or tupac?

Dr. Dre did not rap directly with The Notorious B.I.G. or Tupac Shakur on their own tracks, but he was part of the broader West Coast hip-hop scene that included both artists. He collaborated with Tupac on the iconic track "California Love." While Dre and Biggie had mutual respect and were contemporaries, they never recorded a song together before Biggie's death.
