The Vampire singer shared a video captured of the wholesome moment to her Instagram story on Thursday AEDT.

"Maybe my favorite thing to ever happen at a show omg," Rodrigo captioned the clip.

The heartwarming exchange happened after the fan, named Savannah, held up a sign in the crowd reading: "Olivia, will you do my gender reveal?"

The pop star was quick to accept, reading the gender off of a piece of paper.
