TLC Singer T-Boz -- I'm Getting A Reality Show ... On TLC

Tionne "T-Boz" Watkins -- best known for being one-third of 90's girl group TLC -- is getting her own reality show ... and the network making it happen -- is none other than TLC.

Sources close to the production tell TMZ ... the network has ordered four episodes of Watkins' reality show called "Totally T-Boz" which will air on TLC in 2013.

The timing couldn't be better -- considering T-Boz filed for bankruptcy in late 2011 and could probably use the paycheck.

We're told the show will focus on the 42-year-old single mom as she tries to re-launch her music career ... after recovering from the life-threatening brain tumor she was diagnosed with in 2006.

The brain tumor was so bad, once it was removed, T-Boz had to relearn how to walk and talk.
