Sabrina Carpenter knows how to end a tour with a bang!

The singer brought out pop icon Christina Aguilera for a surprise performance at the first Los Angeles show of the final U.S. leg of Carpenter’s “Short N’ Sweet” tour.

On Saturday, Carpenter shared the unforgettable moment on Instagram with a video captioned: “LA night 1💋 thank you @xtina for coming last night, giving everyone (myself included) the surprise of our lives, and being one of the main reasons I love + wanted to make pop music, I adore you endlessly!!!!!”

The duo performed Aguilera’s classic hit “Ain’t No Other Man” before moving into a rendition of “What a Girl Wants.” This latest performance is inspired by their recent collaboration to celebrate the 25th anniversary of Aguilera’s debut album.

Carpenter surprised fans last month by performing a mashup of her hit “Espresso” with Taylor Swift during Swift’s “Eras” tour stop in New Orleans.

Ahead of the Los Angeles shows, Carpenter teased fans with a photo he posted on Friday, writing: “Tomorrow we start our last three shows of the US leg in Los Angeles. Can’t wait to see you all there 💋 💋: ‘).”

Carpenter will play two more shows in Los Angeles before heading to Europe in spring 2025.
