The "Shake It Off" hitmaker headed to the Nationals Park to deliver another sold-out concert to thousands of fans, reported E!Online.
"They just told me in my ear that I might be stuck up here forever," she told the crowd during her gig.
"This thing is broken. I was just thinking about how I was singing a song about rain and it rained today... It's not that funny... We're just gonna have to rechoreograph the entire show. It's fine. Whatever. It's gonna be a unique show DC!," she added.
