The Saturday fire nearly leveled the 5,000-square-foot mansion, destroying Adkins music awards and all of his family's possessions, The (Nashville) Tennessean reported Sunday.
"You can replace things, not people. I'm just glad that my children are safe," said Rhonda Adkins, who has been married to the star for 14 years.
Two of the couple's children, ages 9 and 6, and the house guests caring for them, escaped the fire unhurt. The family's pets were also rescued.
Rhonda and Trace Adkins weren't home when the fire started, although Rhonda was minutes from her suburban Nashville home when she saw smoke. Shortly after Adkins saw the smoke, a neighbor called her and told her about the fire.
"I'm just numb," she said. "I'm sad because we lost irreplaceable things like all Trace's awards and our family photos."
Trace Adkins was en route to Alaska at the time of the fire and didn't know about it until his plane landed about 11:30 p.m.
The cause of the fire, which started in a garage, was undetermined and fire fighters and investigators remained on the scene Saturday evening.
