When Taylor Swift Brought a Special Guest On Stage, This Grandma Was SHOCKED [VIDEO]

At this point, you go to a Taylor Swift concert just to see what big star she'll bring on stage with her.

Taylor brought her world tour to Nashville this past weekend and she brought the surprises as well!

Friday night, she brought in the one and only, Steven Tyler for a live rendition of "I Don't Wanna Miss a Thing" and the crowd went ballistic.

Then, Saturday night, she brought out MICK FREAKIN' JAGGER! They sang "Satisfaction" together and the crowd LOVED IT.

No one, however, loved it as much as this 72-year-old grandma.

Enjoy!
