Tionne "T-Boz" Watkins, a member of TLC, has withdrawn from touring with the Grammy-winning all-girl R&B group because of her health, she announced yesterday. Watkins, who has been hospitalized for sickle cell anemia, is now pregnant, reports the Associated Press. Touring, she said, is "not healthy, not good and not smart." The Atlanta-based TLC won three Grammys for their album "Fanmail."
