Unfazed, Shania kept cool, chatting with fans during the five-minute period between the primary power going out and the secondary backup kicking in.

As soon as the secondary power source took over, Shania seamlessly restarted the song.

The outage was reportedly caused by an explosion in an office building at the corner of Flower Street and Wilshire Boulevard in Los Angeles just after 10 p.m., leaving four people injured. The cause of the reported blast is still under investigation.

Shania later tweeted about the incident, showing that she had a great time despite the mishap.

"We had so much fun in L.A. that we blew the power out!" she wrote. "We came back up within minutes and kept rocking."

Power plays a bigger part than ever in the singer's Rock This Country farewell tour, as she told ET earlier this year.

"We're punching it up with more pyro, and the light show is like a firework show itself," Shania said. "It looks very colorful and dynamic."
