Ten years ago, Miley Cyrus embarked on her first tour. It was, she agrees, a little less demanding than her current Bangerz production.
"I was the opening act," she remembers. "We had no budget. No one cared I was there and my big entrance was literally from behind a sheet, but it wasn't big enough so my mum sewed two together.
"My big entrance was two dancers dropping it," she laughs.
These days, Cyrus puts on a show that makes a little bit more of a statement. For starters, she arrives on stage by sliding down a giant pink tongue - a reference to that obscene gesture she had a habit of making in public appearances a few months back.
Later on in the show, Cyrus twerks on top of a "car boat", floats above the audience on a giant hot dog, and dances next to an inflatable dog - a tribute to her late pet dog Floyd.
