We have a new addition coming soon," the Cosby Show actress wrote. "Tune into [podcast] #KandidlyKeshia this week for the details!!" But on Monday, just over a week later, Hartwell filed for divorce, Page Six reports. And, via his rep, the former NFL linebacker tells TheYBF.com, "Right now, the only thing I want is a paternity test for the baby." Pulliam and Hartwell dated for four months, got engaged last December and married days later, and Pulliam's baby girl is due in January. In his divorce filing, Hartwell cites "constant disagreements on life changing decisions that couples typically make together." People reports that he is "demanding" a paternity test.
