It wasn't her birthday - but that didn't stop Charli XCX from celebrating like it was at her first New Zealand show.
The UK pop star arrived on stage during the encore at last night's Powerstation show dressed like a birthday cake - then made up raps about the iced treat during a bonkers version of her chart-topping hit with Iggy Azalea, Fancy.
She soon explained why she was wearing the outlandish fancy dress: it was her bassist's birthday, and she celebrated by bringing out a birthday cake, getting the crowd to sing Happy Birthday and delivering an impromptu version of rapper 50 Cent's hit In Da Club.
The show - a free event for iHeartRadio listeners and sponsored by 2degrees - was a punchy and powerful display from an emerging pop talent, who showcased many of her biggest hits backed by a three-piece all-girl band and a glitzy, glam-pop stage show.
