The 24-year-old pop star will accompany Taylor Swift on the remainder of her Latin America Eras shows.
The pop star loves making special moments for her smaller fans.
She finally got to wear her creation to Wednesday night's (Aug. 9) show at Los Angeles' SoFi Stadium.
Wednesday's (Aug. 9) surprise songs included two "New" tracks, though the real highlight was the superstar's blockbuster "1989" announcement.
The 122-track playlist, of course, is called "Starbucks Lovers."
On the new Pop Shop Podcast, Katie & Keith talk about heading to LA's SoFi Stadium to see the Eras Tour after taking a field trip to Las Vegas' Allegiant Stadium back in March.
Monday's surprise songs included an acoustic debut & a solo debut, with a particularly poignant "Exile" sing-along.
Taylor's SoFi Stadium kickoff had its share of memorable moments.
Gracie Abrams will join the extended trek as opener.
The U.S. leg of the tour wraps this month with six Los Angeles shows.
