Country singer Jake Flint died just hours after his wedding on Saturday, his publicist, Clif Doyal, told The Oklahoman. 

Flint was 37 years old. 

While the official cause of death has yet to be released, Doyal told The Oklahoman that Flint died in his sleep following his wedding on Saturday. 

"He was not only a client, he was a dear friend and just a super nice guy. As you can see from the outpouring on social media, he was loved by everybody. I think a lot of it was just that he was a people person, and he had an amazing sense of humor. He made everybody laugh, and he made everybody feel welcome," Doyal told The Oklahoman.  

Doyal told E News in a Wednesday statement that Flint was "a prolific songwriter, recording artist, and in-demand live performer throughout the Midwest and Southwestern U.S."

He continued: "As a testament to his kindness and humanity, he was also a tireless supporter of his fellow artists, always willing to lend a hand to help anyone who needed it. With his infectious smile and disarming sense of humor, he was loved by many, and I believe that, along with his music, will be his lasting legacy."

Doyal did not immediately respond to Insider's request for comment. 

Flint's wife, Brenda Flint, shared a video on Facebook on Monday of the couple dancing and goofing around at their wedding. 

"I don't understand," Brenda Flint captioned the video. 

In a Facebook post on Tuesday, Brenda Flint said, "We should be going through wedding photos but instead I have to pick out clothes to bury my husband in."

"People aren't meant to feel this much pain," she added. "My heart is gone and I just really need him to come back. I can't take much more. I need him here."

Brenda Flint did not immediately respond to Insider's request for comment. 

Flint's former manager, Brenda Cline, also shared the news of Flint's passing on Facebook Sunday, saying, "I loved him much like a son." 

"The funniest, most hilarious, hardest working, dedicated artist I have ever worked with in my career. We were just about to embark on some business together after he and Brenda got married- which was yesterday," Cline wrote.

Brenda Cline did not immediately respond to Insider's request for comment.

According to his website, Flint was a "Red Dirt singer/songwriter who resides in rural Mounds, Oklahoma."

Flint was in the middle of a multi-state tour that was set to continue following his wedding. His most popular singles include"What's Your Name?" and "Hurry Up and Wait."

Flint started playing music after his father was diagnosed with ALS, his website said. Worried that he would not be able to play sports with his son, Flint's dad asked some friends to teach his son to play guitar and take him to Bluegrass festivals. Both father and son bonded over their love of music.
