NASHVILLE (AP) — A Tennessee judge has ruled that three of country singer Glen Campbell's children can contest the validity of two wills that excluded them from any inheritance.

The Tennessean reported Wednesday that Judge David Randy Kennedy issued the ruling this week. Campbell died in August 2017 at age 81. His hits included songs such as "Rhinestone Cowboy."

Kennedy's ruling says Travis, Kelli and Wesley Campbell intend to contest the singer's capacity to agree to the 2001 and 2006 wills that omit them.

The ruling says the three siblings also will contend that their father, who had Alzheimer's disease, was subject to undue influence. A 2006 will was filed by Campbell's widow Kimberly, who was named executor of his estate. That will lists Kimberly and five other children as beneficiaries.
