Tiana thought she’d gotten away with skipping study for her English exam to attend a Katy Perry concert — that is, until she was unexpectedly called up on stage.

The Aussie schoolgirl and her friends Elie, Nour, and Perla ended up sharing the spotlight with the pop icon during her Lifetimes tour stop in Sydney.

When Tiana admitted to the Firework singer that she had ditched her study session, Katy responded with something unforgettable.

Please, Miss Eunice, show us a little kindness,” the pop star pleaded before handing the phone back.

She and her friends showed up in their concert outfits, ready to relive and share every moment of their unforgettable night.
