The country singer was reportedly set to perform Keith Urban's "Kiss a Girl," but attendees had no idea she would take the lyrics to heart showing up in full KISS attire — wigs, makeup and all.
Swift tweeted the next day, "Last night on tour with Keith Urban. Pranking is a must. How about rushing his stage during 'Kiss a Girl' dressed like this? It went down."
The only problem with the prank — no one told Urban it was happening! The Australian superstar appeared confused about the opening act antics and definitely had a few laughs about the heavy-metal interpretation of his lighthearted song.
