The Boys Round Here hitmaker and his wife of four years shocked fans by announcing their split last Monday (20Jul15).

Just days later, on Friday (24Jul15), Shelton took the stage at the Country Jam USA music festival in Eau Claire, Wisconsin, but luck was not on his side as a storm started to roll in.

Shelton was only 45 minutes into his set when the bad weather forced him and his band to leave the stage, and one fan tells People magazine that he even told the crowd, "This isn't my week."

The singer later took to to share a photo taken from the audience, which shows him on stage with a huge lightning bolt streaking the sky behind him.

He wrote, "Sorry we got cut short Eau Claire! Next time we'll make up for it!!!"
