The "Blank Space" singer, who is on her 1989 World Tour, was performing at Nationals Park in Washington, D.C., on Monday when she found herself, stuck on an extendable stage which had suddenly working.
"I'll just be here forever. Stuck up here, unless I choose to jump down," Taylor told the sold-out crowd while laughing. "But in the meantime, I'm gonna sing a song for you called 'Clean' and I hope you'll sing along."
The 18-year-old New Zealand pop star took the stage as the crowd went wild, and performed her hit song "Royals" with the 25-year-old Swift. So even without the unexpected hiccup, it was already an unforgettable night.
