Blake Shelton Pays Tribute to Late Brother Richie

"He's still my hero," he said.

"Wow...25 years ago today we lost my brother Richie Shelton. He's still my hero going strong. Wish everyone could've known him," he wrote on Twitter.

Shelton grew up in Oklahoma and is the youngest of three kids. He spoke out about his brother's 1990 car accident last year to "60 Minutes." Richie died when Shelton was 14 years old.

"I remember picking up the phone...to call him, to tell him something I just saw on TV or, and it was like constantly a shock to me that he was dead," he said in the interview.
