MTV News Online's Kara Manning reports on the latest TLC dispute, as T-Boz says sickle cell anemia will keep her from touring with the R&B group in the future.

The future of TLC as a live act has been thrown into question with the report that Tionne "T-Boz" Watkins says she won't tour anymore because of her battle with sickle cell anemia.

T-Boz, who is pregnant, has been hospitalized several times because of the chronic blood disease and said she decided to quit touring after TLC taped a pay-per-view special at the end of their 2000 Fanmail tour, according to the Associated Press. T-Boz said she barely finished the performance and went directly from the stage to the hospital, AP reported.

A LaFace Records spokesperson refuted the AP story and said TLC will tour again.

One year ago T-Boz explained at the Fanmail tour press conference how sickle cell anemia affected her life.

"With my disease, a lot of things can trigger a crisis," she said. "Stress, my diet, the things I choose to eat, which I haven't done right in the past, but I'm getting better on that ... I have to keep my stress low, which is hard in this business, but I do manage."

The disease, which afflicts one in 400 African-Americans, isn't keeping T-Boz out of the studio. Her solo single "My Getaway" appears on the soundtrack to the movie Rugrats in Paris, due in November.
