Olivia Rodrigo sent her fans into a tailspin as she treated her Melbourne fans to a very rare performance on Thursday night.
The American pop star, 21, put on an epic show when she took to the stage at the Rod Laver Arena for the second night of her Aussie Guts tour.
But one moment in particular sent the crowds completely wild as she treated them to a surprise performance of one of her rarely performed numbers.
As well as her usual set list, Olivia belted out her ballad All I Want, which is sang by her character Nina in the hit program High School Musical: The Musical: The Series.
It is believed to be the first time that Olivia has performed the track on her Guts tour as she doesn’t usually perform songs from the Disney+ series live on stage.
Dressed in a glittering mesh chainmail-style dress, Olivia sat cross-legged on stage and belted out the lyrics alongside her guitarist, with the crowds singing along.
Footage from the standout moment was shared to TikTok by concertgoer Katerina Walczak and sent Olivia’s fans worldwide into a complete frenzy.
Many shared their jealousy that they hadn’t seen the singer perform All I Want at other live shows as they gushed over the milestone moment.

She will perform at four sold-out shows at the Qudos Bank Arena on October 17, 18, 21 and 22 for thousands of eager fans who managed to get their hands on tickets.
New Zealand singer-songwriter Benee is opening all of the shows and the tour comes after Olivia was forced to cancel a visit Down Under last year.
The tour supports Rodrigo’s second critically acclaimed studio album Guts, which bagged her six Grammy nominations, including Album of the Year and Song of the Year.
In her first arena tour to date, she has filled out some of the world’s most famous venues including Madison Square Garden in New York and London’s O2 Arena.
