Reggie Bush is living in a world of uncertainty, because a woman claims he's the father of her unborn baby ... sources tell TMZ Sports.
The woman -- Monique -- is a nightclub waitress who lives in Miami. Our sources say early on in her pregnancy, she contacted Reggie and there were discussions about terminating the pregnancy in return for a large payment. We're told ultimately the discussions went nowhere.
Our sources say Monique, who is now 6 months pregnant, has lawyered up, but this time around it's about child support.
