TLC's raspy voiced singer Tionne "T-Boz" Watkins revealed that she previously suffered from a brain tumor for three years. The 39-year-old mother kept her medical condition under wraps and underwent a seven-hour surgery to remove the grapefruit-sized tumor in 2006. "People are floored when I say I have a brain tumor. I won't let you feel sorry for me," she said. "We'll make jokes, get through it, and the bad stuff will just be a memory."

Despite her medical condition Watkins competed on the 'Celebrity Apprentice' reality show last year. "I didn't want pity," she says of appearing on the show. "I was there to help sick children. I'm still here. It will take way more to stop me."

Watkins also suffers from the blood disorder, sickle cell anemia and is a spokesperson for the Sickle Cell Disease Association of America. In 2002, she spent four months in the hospital due to a flare-up of the disease.

On the music side of things Watkins is hooking up with fellow TLC member Rozonda "Chilli" Thomas for their first concert in seven years. The two will perform at the "Justin Timberlake and Friends" benefit concert on October 16 in Las Vegas.
