Blake Shelton's father, Dick Shelton, has died after his health has slowly declined over the past year. Dick Shelton died at his home in Oklahoma on Tuesday night surrounded by his loved ones, according to a statement on Blake Shelton's website.

"I appreciate your understanding during this difficult time and thank you all for your prayers," Shelton said in the statement. "Your support means the world to me. I love you guys."

Blake Shelton and wife Miranda Lambert, a Lindale native, have both been silent on Twitter since Monday.

Shelton has postponed four dates on his Well Lit and Amplified Tour this week, all of which will be made up in March. You can see the rescheduled dates here.

Shelton dedicated his win at the American Country Awards in December to his father, who was hospitalized earlier that day for pneumonia.
