First comes divorce, then come the legal battles. For Billy Ray Cyrus, his latest round of trouble has little to do with his recent split from Leticia "Tish" Cyrus. The country singer's 61-year-old former road manager, Paul A. Abraham, is suing him and his estranged wife, claiming they fired him due to his age.

The lawsuit was filed late Monday (Jan. 10) in Davidson County Circuit Court, according to The Tennessean. According to the filing, Billy Ray said Paul was “old and dumb and don’t know anything about running a farm.”

In addition to his touring duties, Paul worked primarily in Tennessee at the Cyrus farm known as “Singin’ Hills.”

He was fired on May 1, 2010, the lawsuit states.
