Kelly Clarkson’s voice has taken her all around the world – but her dance moves are another story.
Clarkson, 31, recently visited coffee farms and performed a special set for farmers and their families in Peru.
“It was so funny cause I didn’t know if they were gonna like my songs. They would sing along, I think we did like a mini-set for them, so we did a few songs down there. They were dancing, it was just so cool! I felt like I was just in a movie,” Clarkson tells PEOPLE of the performance. “I was dancing with them!”
Her trip, part of Green Mountain Coffee’s Great Coffee, Good Vibes, Choose Fair Trade campaign, was an eye-opening experience for Clarkson.
“I didn’t know that a lot of them didn’t have electricity,” she says. “That’s the one cool thing that was for me to learn with this opportunity, [through Fair Trade] they have more opportunity with their whole community. They have more education and more access to electricity. It’s a better way to further the community. I felt like I was actually making a difference, which is something I think we all want to be a part of.”
While the acoustic performance brought Clarkson’s audience to their feet, the singer says she couldn’t quite keep up with their moves.
“I couldn’t do their steps,” Clarkson confesses. “I was totally not Beyoncé. They all had these cute dances they were doing together I just started doing the sprinkler and the running man.”
But when it comes to dancing on her big day – her upcoming nuptials to fiancé Brandon Blackstock – the singer has the perfect song all picked out.
