Derrick Rose tweeted photos of his newly born baby on with the message: "My lil man PJ," Chicago Sun-Times reports.
During promotional interviews for his shoe, the Bulls guard has alluded to becoming a father a few times but has kept the details private. Mieka Reese, Rose's longtime girlfriend, is the mother.
Rose has been rehabbing a knee injury from last season and is not expected to return until February.
The Bulls confirmed that the boy was born about two weeks ago but had no other information.
