Carrie Underwood isn't the only country star to recently get her rock on with the Rolling Stones!
Monday night, Taylor Swift joined Mick Jagger and company on stage at the United Center during their concert in Chicago.
She sang their song "As Tears Go By" with the band.
Fans weren't too surprised by her appearance though. Mick tweeted that she was making an appearance at the show and asked fans which song they should perform.
Taylor also tweeted about the performance. "Filing this under 'never in my wildest dreams'.Thank you @RollingStones for inviting me to Chicago to sing with you," she posted.
