Moves like Jagger! Taylor Swift joined Mick Jagger on stage for a duet at the Rolling Stones concert in Chicago on Monday, June 3.
Wearing a sexy little black jumpsuit with her long blonde locks styled down, Swift, 23, showed off her dance moves while singing "As Tears Go By" with Jagger, 69. A version of the classic rock ballad -- written by Jagger, Keith Richards, and their manager Andrew Long Oldham -- was first released by British singer Marianne Faithfull, Jagger's then-girlfriend, in 1964, and the Stones a year later.
"Yes, I just did gyrated on Mick Jagger. What?!" she tweeted after the May 11 show. When a fan called her out on her poor grammar, Perry, 28, wrote back, "I noticed that. I guess I was too excited. Sorry mom."
