SALT LAKE CITY (AP) - George Virgil Osmond, a Wyoming native who was father of the famous singing family The Osmond Brothers, has died.

Osmond passed away Tuesday morning at his home in Provo, Utah. He was 90 years old.

A cause of death was not immediately available.

Family spokesman Kevin Sasaki told The Associated Press Osmond likely from natural causes incident to his age, as he had not been ill.

"I spoke to Jimmy Osmond, and he said his father had a great day yesterday and was in good spirits," Sasaki said.

The death was first reported by "Entertainment Tonight's" Web site and was confirmed by the AP through a spokeswoman for The Church of Jesus Christ of Latter-day Saints, of which Osmond was a member.

Donny Osmond was in the ET studio getting ready to tape a segment for a show when he learned of his father's death. Marie Osmond performed Monday night on "Dancing With the Stars."

George Osmond was born Oct. 13, 1917 in Star Valley and liked to be known as "The Wyoming Cowboy," according to a news release issued by the family. A World War II veteran, he also served missions for the Mormon church in Hawaii and the United Kingdom.

Osmond married his wife, the former Olive Davis, on Dec. 1, 1944. She died in 2004.

The couple were the parents of nine children, many of whom became singing stars.

In his professional life, Osmond worked in real estate, insurance sales and was once the postmaster for the city of Ogden. He gave up his work to manage the singing careers of his children.
