A heartbreaking new video has emerged showing country singer Jake Flint serenading his new bride just hours before he died in his sleep at the age of 37 on Saturday night. Flint passed away following his wedding in the some town of Owasso, Oklahoma - 15 miles outside of Tulsa. His cause of death has not been made public. His death was confirmed by his wife, Brenda, in a series of heart wrenching Facebook posts. B.TV has also obtained exclusive photos of the wedding reception, showing Flint and Brenda, wearing a denim jump suit with a floral pattern on the side, smiling from ear-to-ear with their guests. In the new video, Flint can be seen strumming an unknown ballad while his wife literally swoons alongside him, singing along with some of the lyrics. The clip ends with Flint singing: 'Boy, I found me a keeper, the day I made her my wife.' The video was posted by another Oklahoma-based musician, Mike Hosty, who wrote in the caption: 'He grabbed a guitar and sang a song to his bride in the barn.' The same video was also posted by Flint's mother, Teresa, who wrote of her late son: 'Through the tears, my son makes us all smile. His antics onstage were always entertaining and his jokes always corny.'
