Taylor Swift took over New Orleans Saturday night, with an assist from Sabrina Carpenter.
T.S. hit the stage at the Caesars Superdome for her "Eras" tour and performed a slew of hits when she grabbed a cell phone in front of 65,000 screaming fans and gave Sabrina a jingle ... then summoning her to the stage.
Sabrina obliged and she and Tay sang a duet, which made the crowd go even more insane.
As you know, early on in the tour -- the summer of '23 -- Sabrina opened for Taylor and continued doing so for months.
The hit-making duo proceeded to perform a mash-up of three of their big hit songs for the enamored crowd.
Sabrina performed "Espresso" -- an acoustic version -- which then became part of a mashup with Taylor's "Is it Over Now?"
One funny thing ... Sabrina -- who's much shorter than Taylor -- came out in a pair of ginormous platform shoes!
In all, T&S did 3 mashups, which included Sabrina's "Please Please Please."
Taylor has another show in New Orleans tonight, and then she'll head to Indianapolis, and then she's off to Canada.
