Star struck? Ever so slightly. It’s not every day that you get to meet – apologies to Taylor, Miley, Lana, Beyoncé etc. – the hottest pop star on the planet. And with oodles of credibility to boot. We’re backstage at Electric Picnic where in just over three hours, Eilish will play to one of the biggest Main Stage audiences ever - and get a humongous roar when she mentions her Irish roots. Photos don’t do justice to her hair, which is a none too delicate shade of neon green, and appears to radioactively glow every time the sun hits it. I’m not sure I could pull the look off myself, but on the prodigiously talented 17-year-old it’s stunning.

Accompanied by her mum, dad and elder brother Finneas, of course, Billie arrived in Dublin yesterday afternoon. Time has been tight, but they managed to drive round the Phoenix Park, which she proclaims to be “stunning.”

“We saw some deer, which you don’t get too many of in L.A.,” she jokes. “It was really pretty. Our hotel’s right next to the river, which looks incredible. I don’t really get to walk anywhere these days, but I get the sense that it’s a great city to just dive into and explore.”
