If you think Taylor Swift's 1989 World Tour and all those star-studded cameos are slowing down anytime soon, you're wrong. Her concerts at Nashville's Bridgestone Arena this weekend were packed with guest appearances. On Saturday the Grammy winner got some major satisfaction when the legendary Mick Jagger stopped by.

The Rolling Stones frontman joined Swift for a rousing rendition of "(I Can't Get No) Satisfaction" and, of course, the audience went crazy for it. Watch a fan video of the performance here:

Swift later shared pictures of the pair and tweeted "drops mic":

Leona Lewis also came out during the Saturday show and sang "Bleeding Love" with Swift, who shared a photo of the memorable experience. "Me losing my mind because @leonalewis is singing 'Bleeding Love' and it's the most glorious, beautiful thing I've ever heard or seen," she captioned the Instagram post:

She also shared a video of the performance:

It was a busy weekend of guest appearances for Swift with Steven Tyler joining her on stage at the Friday concert to perform Aerosmith's 1998 power ballad, "I Don't Want to Miss a Thing." Both artists loved the experience and filled their social media accounts with praise for each other:

Are there any singers left in the world who haven't appeared on Swift's 1989 tour? We can't wait to find out who'll be next: She performs in St. Louis, Mo., tonight.
