Blake Shelton performs at first concert since split

Singer Blake Shelton looked to be in good spirits when he took to the stage to headline the Country Jam USA music festival.
This was his first performance since news broke of his divorce from wife Miranda Lambert last week, reported Us magazine.
The 39-year-old country superstar played a 45-minute set at the Eau Claire, Wisc, festival before thunder and lightning forced him to end the set early.
"Sorry we got cut short Eau Claire... Next time we'll make up for it!," he tweeted to his 13 million followers.
At one point during the show, Shelton, 39, joked, "Man, this isn't my week" when the TV cameras failed to scan the crowd when he asked them to.

The country power couple announced their decision to call it quits on their four-year marriage on July 20.
