Taylor Swift is full of praise for her former Eras Tour opener Sabrina Carpenter, dubbing the “Please Please Please” singer “the pop princess of our dreams” after Carpenter joined her as a surprise guest in New Orleans over the weekend.

“Wow, New Orleans. I’m still smiling thinking about that wonderful weekend,” Swift wrote in an Instagram post reflecting on the memorable performance.

“The city really welcomed us with open arms (with friendship bracelets on those metaphorical arms) and celebrated the tour with such flare. One of the things I’ll always remember from this weekend was getting to surprise the crowd with a performance by the pop princess of our dreams: @sabrinacarpenter.”

Swift, who has a long history of bringing special guests to her stage, took the opportunity to praise Carpenter’s work ethic, noting her commitment to creating a special moment for fans despite her demanding schedule.

“Side note: She had one day off from her very exhaustive tour schedule. Her show is physically full on and spectacular, and she could’ve been resting in her time off. One of the reasons I respect her so much is that she does things like this, goes out of her way to give fans a surprise moment they didn’t expect,” Swift continued. “She’s as real as they come and I’m so thankful she did that for us.”

Swift and Carpenter have dominated the Billboard charts in 2024. Swift’s record-breaking run includes a dozen No. 1 singles on the Hot 100, with recent back-to-back hits “Cruel Summer” and “Is It Over Now?”—making her the only woman to ever replace herself at No. 1 twice.

For Carpenter, who kicked off her rise as an Eras Tour opener, this year has been massive. Her album Short n’ Sweet has held No. 1 on the Billboard 200 for four non-consecutive weeks, and “Espresso” became her highest-charting song yet.
