Miley Cyrus shares her grueling work schedule when she was just '12 or 13,' including waking up at 5:30 a.m., 9 interviews, and several photo shoots

• Miley Cyrus looked back at her work schedule during her "Hannah Montana" days in a new TikTok video.
• Her demanding 12-hour day began at 5:30 a.m. and included nine interviews and two photo shoots.
• Her mom, Tish Cyrus, noted in the video: "That truly was the next four years of your life."

Miley Cyrus recalled the grueling work schedule she had during her early teens thanks to her star-making role in the Disney Channel series "Hannah Montana."

In a series of videos uploaded to TikTok, inspired by her reflective new single, "Used To Be Young," the 30-year-old star has been delving into her past and her career evolution, discussing everything from her decision not to tour since 2014 to her relationship with her country star father, Billy Ray Cyrus

In the latest video in the series, shared on Tuesday, the singer walked her followers through a typical day she experienced as a child star.

The "Flowers" singer was just 13 when she was propelled to fame playing Miley Stewart, a girl from Malibu experiencing the "best of both worlds" as a normal teenage girl by day and a famous pop star by night.

However, for Cyrus herself, it seems that there wasn't a lot of time left in her day for typical teenage pastimes, given how much press she had to do to promote herself and the show.

Reading from a tablet, Cyrus rattled off one of her old schedules from when she was around 12 or 13, which kicked off at 5:30 a.m.

The day began with "hair and makeup in my hotel," before she was picked up at 7 a.m. to appear on the news.

After this, Cyrus said that she had another three live interviews at 7:45 a.m., 8:15 a.m., and 8:45 a.m., and a 90-minute "meeting with editors," all before making it "back to the hotel" for noon.

However, Cyrus wasn't given any respite over lunch. Reading the next thing on her schedule, she said: "OK, I have to do an interview but the reporters are all fifth-grade students."

After this, she had a "lunch interview" with her dad at the hotel, per the schedule, before leaving the hotel again to go to a photo shoot for Life magazine.

This was followed by another photo shoot and interview, this time with the "Achy Breaky Heart" singer for the Father's Day issue of an unnamed publication, for two hours between 3 p.m. and 5 p.m.

To round out her grueling 12-hour day, Cyrus had to arrive for a "kids online interview" at 6 p.m., followed by yet another interview at 6.15 p.m.

"Then the next day starts at 7 a.m. and ends at 7:30 p.m. when I fly home to probably go to 'Hannah,'" she said. "That's on a Saturday and then Monday be back at work in the morning."

After looking back at her younger self's intense work schedule, Cyrus said: "I'm a lot of things but lazy ain't one of them."

Off-camera, Cyrus' mom, Tish Cyrus, chimed in to add: "That truly was the next four years of your life."

"So, I do think this girl deserves a little endless summer vacation," Cyrus concluded.
