At her concert at the Bridgestone Arena in Nashville on Friday, the 25-year-old pop star brought onstage Steven Tyler, 67, to perform a duet of his band Aerosmith's 1998 hit ballad "I Don't Want to Miss a Thing," from the movie Armageddon.
"HOLY SWIFT!!! @TAYLORSWIFT13 ...SHINED SO HOT N BRIGHT SHE MADE THE SUN JEALOUS!!!" the rocker said on his Twitter page. "THANKS FOR THE FUN."
He also retweeted a 2012 post Swift had published, in which she said, "I feel like I'd be more understood if people knew 'I Don't Want to Miss a Thing' by Aerosmith is how most of my emotions sound in my head."
"WELL MA DARLIN'...YOU SURE WERE OVERSTOOD TONIGHT! A++...EPIC SHOW...UNTIL NEXTIME..." he wrote in response on Friday.
Swift posted a video of their performance.
"Singing 'I Don't Want to Miss a Thing' with @IamStevenT was an honor," Swift tweeted. "So inspired by how sweet he was to all of us."
