They love to team up with various artists during their wildly popular shows, and The Rolling Stones invited Taylor Swift to join them for their gig last night (June 3) in Chicago, Illinois.

Taylor Swift hottie showed off her long legs in a sexy black dress as she strolled out and sang “As Tears Go By” with Mick Jagger and the boys.

And after the performance, T. Swizzle took to her Twitter account to gush about her once-in-a-lifetime experience.

Taylor tweeted, “Filing this under ‘never in my wildest dreams.’ Thank you @RollingStones for inviting me to Chicago to sing with you.”
