Sydney, Australia - Singer Olivia Rodrigo just created a hilarious and cringe-worthy moment on the GUTS World Tour stage that's currently blowing up on TikTok.

During a recent Sydney show, the vampire artist spotted what she thought was an adorable couple in the audience.

"You guys are so cute!" Olivia declared, adding, "How about a kiss for the jumbotron? Let's spread some love!"

However, little did she know – the "couple" were actually siblings!

"She's my sister!" the boy instantly screamed, per a video recording of the event.

The girl next to him turned bright red and the crowd erupted in laughter.

Liv, like the pro she is, recovered pretty quickly, yelling, "SHE'S YOUR SISTER?! OH S**T! OKAY NEVERMIND, NEVERMIND SCRAP THAT."

Thankfully, the boy – now identified as Tom Santo – managed to capture the entire thing on camera and posted it on TikTok with the caption: "Olivia Rodrigo asking my sister and I to kiss was not on my 2024 bingo card."

Olivia commented, "I AM SO SORRY!"

Her four-night stay in Sydney will end on October 22, and then the singer will be performing a limited run of shows in Latin America in early 2025.

Who knows what other hilarity the 21-year-old artist will get herself into in the concerts to come?
