Blake Shelton: a look back at the 'coolest and craziest' thing he's done in his life

To have Gwen Stefani come out and shock everyone at his show was the 'coolest and craziest' thing Blake Shelton ever did in his entire life.

On his 40th birthday in 2016, Shelton performed at the music festival Country Jam in Grand Junction, Colorado.

The audience erupted in applause and cheering when Stefani walked on the stage. Though not always, the Hollaback Girl singer usually treats the crowd to a performance every time she attends Shelton’s shows.

The couple then performed their duet, Go Ahead and Break My Heart. They co-wrote the song for Shelton’s album, If I’m Honest, in 2016.

Shelton and Stefani place their love on full display whenever they sing it. Throughout most of the song, they just keep staring and smiling at each other. The couple made it obvious they were having a wonderful time together.

After their performance, Stefani stunned the crowd with her song Hella Good. The audience was loving it, especially the God Gave Me You singer.

“What just happened?! I don’t know how I’m gonna follow that,” Shelton told the crowd right after his girlfriend's performance.

Shelton said that he wishes he was the type of musician that could also rock.

'I possibly witnessed the coolest and craziest thing of my life tonight.... Thank you Colorado and @gwenstefani!!!' Shelton tweeted of the performance.

In an interview with Chelsea Handler on her Netflix talk show, the country superstar revealed how he really feels about that performance.

“I’m doing my normal, you know, what I think is rockin’. Standing up there with my acoustic guitar in front of my stand and singing my songs,” he told Handler. “I had my band work up one of her songs, ‘Hella Good.’ And I thought ‘Man, that’d be so cool to have her come out and surprise.’ It’s the worst thing I could have done because all it did was make me look terrible.”

Shelton and Stefani fell in love while serving as coaches on The Voice. Both of them announced their split from their former spouses a few months earlier.
