The two are not brothers, though Fat Joe referred to Pun as his ’twinsito’.
Big Joe was born Joseph Antonio Cartagena on August 19, 1970 in The Bronx, New York. He is of Cuban and Puerto Rican descent. Big Pun (Christopher Lee Rios) on the other hand was born on November 9, 1971 in Bronx, New York.
In 1998, Pun and Joe became inseparable, touring and appearing together all over the country, and as Joe helped integrate Pun into the business of rap, Pun helped Joe elevate his rapping prowess above just “street” anthems.
They routinely referred to each other as “twin,” in reference to their close relationship. They even faced the music of the law together, turning themselves in to police on Sept. 8, 1998, for assault charges.
Sadly Pun was taken from this Earth too soon. He died of a heart attack on February 7, 2000.
