The name Tammy Wynette no longer appears on the country singer's tombstone.
Broadcast reports say the name was recently changed from "Tammy Wynette" to "Virginia W. Richardson."
The Country Music Hall of Famer was born Virginia Wynette Pugh but her stage name was always Tammy Wynette.
She married George Richie in 1978 and was married to him at the time of her death in 1998.
There was no immediate word on why the name plate was changed.
Wynette's tomb is at Nashville's Woodlawn Cross Mausoleum.
