US Singer and TV personality Marie Osmond and husband Brian Blosil are divorcing after 20 years of marriage, the pair has announced.

Osmond, 47, earned fame aged 13 with the hit song Paper Roses, and starred with her brother, Donny, on the Donny and Marie Show during the 1970s.

Osmond and Blosil, a record producer, married in a Mormon ceremony in October 1986 and briefly separated in 2000.

They have eight children, some of whom are adopted.

In a statement released by Osmond's publicist, the couple said: "Though our marriage is ending, we continue to have a very amicable relationship.

"Our marriage has always been a faithful one and neither of us is assigning fault for the divorce."

Osmond and her first husband Stephen Craig divorced in 1985.

She also owns a successful collectibles doll company.
