His sister Mary Huston says Sharp died in Fair Oaks, Calif., at 10:49 p.m. Saturday of complications from past stomach surgeries and digestive issues.

Sharp gained fame with the release of "Nobody Knows," a number-one single on his 1996 debut album "Measure of a Man." He released two other albums, "Love Is" in 1998 and "Make A Wish" in 2005.

Born in 1970 in Redding, Calif., Sharp was diagnosed with Ewing's sarcoma, a rare form of bone cancer, which he overcame after two years of chemotherapy and radiation.

Sharp became a motivational speaker, a spokesman for the Make-A-Wish Foundation and wrote "Tragedy's Gift," a 2004 book about fighting cancer.
