“5.30am?!” Cyrus exclaimed, reading a list of one day’s engagements. “I’m probably 12 or 13. Friday, January 5th, 5.30m — hair and makeup in my hotel. 7am — we get picked up. 7.15am — I’m on the news. 7.45 — I have another live interview. 8.15 — another interview. 8.45 — another interview. 9.30 to 11am — meeting with editors, back to the hotel.”
