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.
