Earlier this month (June 3), country-pop superstar Taylor Swift joined Mick Jagger and the Rolling Stones on stage for a joint performance and described the experience as 'career defining'. 

During an interview with Access Hollywood, the 'I Knew You Were Trouble' beauty explained that their Chicago concert, where she joined the iconic rockers for a rendition of 'As Tears Go By', was "wonderful" and she loved playing off Jagger's magical energy:

"The whole band, they're so welcoming and wonderful and approachable and all the things you would hope your heroes would be. It's wonderful getting that phone call. Like, 'Hey, would you like to go and play with the Rolling Stones?' That is a bold, underlined, exclamation point 'Yes'!"

"[Mick and I] did this twirl in the dressing room when we were rehearsing, because we just started sorta kinda like dancing around the room and frolicking and it was really fun."

Swift added: "So we decided to incorporate that into the actual performance... I really wanted to do the twirl - this one little twirl that we did - and that was pretty much the best moment ever." Watch Swift and the Stones' joint performance here:
