Country music hit-maker Joe Diffie died Sunday after complications related to coronavirus, his publicist said in a press release.

A force in country music during the 90s with his iconic moustache and mullet, Diffie made 13 albums with chart-topping songs such as "Pickup Man" and "Home."

The Tulsa native was inducted into the Oklahoma Music Hall of Fame in 2002 and during his career as a singer-songwriter, Diffie earned many accolades including a Grammy and a Country Music Award. He was also a member of the historic Grand Ole Opry for more than 25 years.
