Taylor Swift's Vlog featuring Demi Lovato: "This is a glimpse of what it looked like backstage when we pranked Keith Urban, surprising our crew members on tour, why Demi [Lovato] shouldn’t drive jet skis, and some very fashionable hats modeled by my mom and me. I’m leaving for the UK in the morning, so there’s a shout out to you guys that I’ll be seeing in London and at V-Fest! And it’s all set to ‘One Time’ by Justin Bieber. It’s very much on repeat at the moment."
