Blake Shelton is full of surprises!
On Saturday, the "Boys 'Round Here" singer took to social media to announce that he would be performing an impromptu concert in Birmingham, Alabama, ET has confirmed.
The series of excited, adorable messages started around 10:30 a.m. ET, when the country crooner started tweeting out of boredom.
"Hi.. Sorry I haven't tweeted much lately," he wrote. "Bored today. Maybe I'll do something ridiculous later... #serious."
A fan replied, suggesting that the 39-year-old singer "put on an impromptu concert somewhere…that would be ridiculous!"
Intrigued by the idea, Shelton wrote back, "Hmmm.... That'd be fun. But probably couldn't find a place to do it on this short of notice."
"This might happen.... This just might freaking happen!!!!" he excitedly tweeted. "South. As in THE south..."
Shortly after dropping that bombshell, he updated fans with his major news: He would, in fact, be performing a free show at Iron City, a restaurant and entertainment venue, in Birmingham.
The announcement got fans stoked, but many wondered if the Voice coach was being serious.
"Really?" one Twitter user asked. "Really," Shelton quickly responded.
The venue confirmed the show was officially a go, announcing on their own Twitter page that the first 1,300 people to show up would be given a wristband.
According to posts on Twitter, fans couldn't get in line quick enough. The venue confirmed to ET that the 1,300 wristbands sold out in just a few hours, causing about 1,000 people to be turned away.
“I watched people running down the street to get in line,” an eyewitness told ET.
It doesn't get much cooler than that!
Shelton loves giving back to his fans. Last November, he rescued a group of four young men who were stuck in a mudslide in his home state of Oklahoma. Watch the video below to hear more.
