While watching Blake Shelton perform on the stage, in Las Vegas, at the iHeartRadio Festival, people were expecting something great - however everything was rather normal.

"It's been a weird year," he told reporters before his performance, "but at least I got my songs coming out."

It was 25 minutes of Blake Shelton on stage. The country singer went through his hits and talked including his favorite hobby: drinking, but never mentioned about his newly single life.

Shelton and wife Miranda Lambert, already announced that they were divorcing in July after four years of marriage. What happened to "God Gave Me You"? Or is it going to be "Lonely Tonight" for Blake?

"They told me I was playing this iHeart music festival and I thought, 'That's pretty cool. I'll go do that. That would be fun, right?'" he told the crowd.

"I never actually know what I'm doing until I get here and I'm like, backstage doing some interview and I'm like, 'Who's that on stage?' That's J. Lo. What the eff? What am I doing here?"

"So then, I just want y'all to know, I got nervous and I'm still nervous right now, and when I get nervous I tend to drink a little bit, okay," he said, raising a red solo cup. "I'm just being honest with you."

Shelton has always shared in his concerts about drinking when getting nervous. He also shared the same thoughts, last July, when he performed at Country Jame USA in Wisconsin.

"I'm nervous tonight and I tend to drink when I get nervous," Shelton told the crowd at the time.

On the other hand, Lambert is doing something helpful. She performed in Luckenback, Texas for a special event for MuttNation Foundation.
