Kevin Sharp, the international country music star, has died aged 43 due to complications related to cancer. Best known for his hit single 'Nobody Knows,' Sharp enjoyed a successful career in music before travelling around America as a motivational speaker and becoming one of the Make-A-Wish Foundation's leading spokespersons.

"We are saddened to announce the passing of Platinum Country Recording Artist Kevin Sharp on Saturday April 19, 2014 at 10:00 pm PST," reads the star's website, before requesting "that if anyone would like to make a donation in Kevin's memory, that donations be made to the closest Make A Wish Chapter in the donor's area so that wishes can continue to be granted for other children."

With the help of many high profile celebrities and benefactors, the foundation works to grant the last wishes of terminally ill children. Sharp himself had battled with cancer as a teenager in the nineties before being diagnosed with Ewing's Sarcoma, a rare cancer that affects the bone and soft tissue.

"He had a strong heart, that's what kept him alive, (but) I'm so happy for him, that there's no more suffering," said his sister, Mary Huston. "His dream came true through music. He touched thousands of lives, and he helped heal the souls of people dealing with cancer," via The Independent.

Born in California in 1970, Kevin spent his younger years appearing in musicals until he was diagnosed with cancer. Against the odds he survived - although permanently lost his hair due to the chemotherapy treatment. Whilst recovering from his illness, he met legendary producer David Foster through the Make-A-Wish Foundation.

After Sharp produced a demo tape Foster helped sign him to Asylum Records in Nashville. In 1996, he released his first album, Measure Of A Man, selling over 500,000 copies, while his first single, Nobody Knows, spent four weeks at the top of the Billboard Hot Country Singles and Tracks chart.

Sharp reportedly died at his mother's house in California where his sister had been caring for him since his release from a 10 week stay in hospital. He had been struggling with past stomach surgery and residual issues from his aggressive chemotherapy and radiation treatment.

"A legacy cannot be created, it is earned and you my friend have earned it many times over. There are people around the world who have been inspired to lead better lives because you touched their life in a special way."

A memorial service held in Nashville is currently being planned.
