Sabrina Carpenter Reveals Her ‘Big Blonde Moment’ When Taylor Swift Asked Her to Perform Eras Tour Mash-Up. Why It Was ‘Genius’

Sabrina Carpenter had a "big blonde moment" while preparing to hit the stage with Taylor Swift.

In episode 4 of Swift's The End of an Era docuseries on Disney+, the 36-year-old pop superstar and Carpenter are seen rehearsing to perform a mash-up of "Espresso," "Is It Over Now?" and "Please Please Please" at the Caesars Superdome in New Orleans in October 2024.

While backstage in a green room before the big moment on stage, Carpenter spoke about realizing why Swift chose to include the 1989 (Taylor's Version) track in between the "Tears" singer's hits.

"Okay, I felt like a real big idiot, ‘cause the first time you sent me the first version, which was so genius, it didn’t process that the ‘takeout coffee’ line really fits with ‘Espresso’ until I literally was in the car on the way here," said Carpenter, who opened for many Eras Tour shows before the New Orleans appearance.

"I was like, ‘She’s so smart.’ But yeah, that was a big blonde moment for me," she continued. "It took me a day."

Swift responded, "No, but what are the chances it has the same rhythm and is in the same key?"

Elsewhere during the episode, the "Karma" singer spoke about what it's like working with Carpenter, whom she featured on the title track of her latest album, The Life of a Showgirl.

"Sabrina is just like a shooting star," said Swift. "She’s so smart, she knows exactly how to entertain people in the way that they want, in the moment that she’s in."

"She’s just like battling herself for No. 1 on the charts all summer," added the 14-time Grammy winner. "And when you see that happen, you’re just like, ‘Go! Fly higher!’ And then it’s even cooler when, like, someone like this will circle back and, like, bless us with their magic."

The third and fourth episodes of The End of an Era premiered on Friday, Dec. 19. The final two episodes will hit Disney+ on Dec. 23.
