Taylor Swift expressed her admiration for Sabrina Carpenter after the up-and-coming pop star made a surprise appearance at The Eras Tour in New Orleans over the weekend.

Taylor took to Instagram to thank her fans for their support during the three sold-out shows in Louisiana.

“I’m still smiling thinking about that amazing weekend,” she wrote in her post.

“The city embraced us wholeheartedly (with friendship bracelets on those metaphorical arms) and celebrated the tour with such style.”

The 34-year-old singer highlighted that Sabrina’s unexpected performance, where they sang a medley of their hits together, is a moment she will “always cherish.”

Taylor described Sabrina as “as real as they come,” adding, “She had one day off from her demanding tour schedule. Her show is physically intense and spectacular, and she could have chosen to rest instead.”

“One reason I admire her so much is that she goes out of her way to create surprise moments for her fans.”

The “Karma” singer concluded by calling Sabrina the “pop princess of our dreams.”
