"I'm starting to get the hang of this Grand Marshal thing ... let's do this Indy!!!!" Shelton writes on Instagram.

As Grand Marshal, the country star had the honor of giving the command for drivers to report to their cars. It's a longstanding tradition during the pre-race ceremonies. Actor Miles Teller served as the honorary starter for the storied race.

Shelton was also a special guest of driver Jimmie Johnson — the two collaborated on a helmet design that Johnson wore on race day.

"Blake is a country music powerhouse and good friend of motorsports fans everywhere," Indianapolis Motor Speedway President J. Douglas Boles said prior to the race. "For both spectators at the track and everyone watching on NBC, his winning energy will be a perfect fit for the intensity of 'The Greatest Spectacle of Racing.'"

Just last week, Shelton was on hand for the pre-race activities for NASCAR's All-Star Race. The event took place on May 22 at Texas Motor Speedway in Fort Worth, Texas. The "Austin" singer had the honor of telling the drivers to start their engines. "Just a totally normal day.. yep.. totally normal..." he joked on social media, sharing video of the big moment.

Shelton has been quite busy outside of the recording studio recently. Without having a spring season of The Voice coaching duties to tend to, he's kept busy with other projects. In addition to a new television show in the works with his The Voice co-worker Carson Daly, the Oklahoma native recently opened a new location of his bar Ole Red in the Nashville airport. Fans can get a taste of Shelton's hospitality in Terminal C.
