Blake Shelton hit the WE Fest 2015 but the memorable event happens to be his final scheduled concert of the year.

Even though it was just recently announced his divorce with his ex-wife Miranda Lambert, Shelton remains strong and professional while singing the first song 'Neon Light' and 'All About Tonight' in front of the crowd in Detroit Lakes, Minn. on Saturday night.

"I'm getting too old for this s-t," the country singer jokes. "But because it's my last concert of the year ... No rules."

While Shelton looks at the WE Festers, who raised their beers in the air and drank up "Look at all these country music freaks in here," the music artist said.

The two-hour set, included several older tunes like 'She Wouldn't Be Gone,' 'Some Beach,''Austin' and 'Ol' Red' with a twist of newer chart-toppers like 'Sangria,' 'Sure Be Cool if You Did' and 'Drink on It,' according to Taste Of Country.

Blake told the thousands crowd, "I have been here before, and I don't think I've seen this many people, Y'all are smashed in here." Adding, "somebody's gonna end up pregnant ..."

Shelton was joined on stage by her former teammate in 'The Voice,' Gwen Sebastian, for the duet "Lonely Tonight" and "My Eyes."

Then Shelton said, "Gwen was on my team during Season 2 of The Voice and she has literally been a member of my family ever since then."

While Shelton is singing 'Home' the sea of crowd held their cellphones and lighters in the air, making a beautiful lightning effect.

Shelton happily said, "We should have televised this concert tonight."

 "It would have been epic," he added.

Blake Shelton wrapped the 2015 WE Fest with "Footloose" and "God Gave Me You." The night was ended with the display of fireworks.
