NEW YORK — Olivia Rodrigo is bidding farewell to her "Guts" era.

The singer-songwriter played her "final" concert following her 102-show, arena-filling Guts World Tour with an intimate "secret" concert in New York City, hosted Thursday night by American Express.

"This is definitely going to be the last 'Guts' show, so it's kind of awesome to bookend this chapter," Rodrigo, 22, said before diving into her first chart-topping hit, "Drivers License." "Can't wait to get back on the road one of these days. I don't think I've ever played a show without playing this song."

The Grammy-winning "Good 4 U" singer, dressed in a sequined chartreuse babydoll mini dress, knee-high socks and Miu Miu ballet flats, played a hit-packed show accompanied by an all-female band. She playfully danced around the stage, belting out songs from "Sour" and "Guts," including "Vampire," "Bad Idea Right?" and "Deja Vu."

The Oct. 23 show also saw celebs like "Emily in Paris" star Ashley Park, "Vampire Diaries" star Nina Dobrev and Good American co-founder Emma Grede in the audience rocking out to Rodrigo.
