T-Boz’s thick appearance prompted a slew of pregnancy rumors on social networking sites Twitter and Facebook last night. T-Boz, 41, suffers from Sickle Cell Anemia and has been in and out of hospitals. In 2009, T-Boz talked about her battle with a brain tumor. T-Boz has a 10-year-old daughter, Chase Anela Rolison, who was fathered by rapper Mack 10.
