Apparently, the rumors of J.J. Redick's secret rap talent are real ... so says DeAndre Jordan.
The hip-hop community has been waiting for Redick's debut album since he teased it back in 2009 ... but he never hit us with that hot fire ... and in the end, people thought it was just a joke.
But not so, says his Clippers teammate DeAndre Jordan -- who hails Redick as the best rapper on the team ... and says, "He can spit."
Hey Redick ... PROVE IT.
