Determining the absolute youngest artist to have completed a world tour is difficult due to the lack of a universally accepted definition of "world tour" and the ever-changing nature of the music industry. However, some notable contenders for this title include:
- Justin Bieber: At the age of 16, Bieber embarked on his first world tour, "My World Tour," in 2010.
- Miley Cyrus: At the age of 16, Cyrus launched her "Wonder World Tour" in 2009.
- Demi Lovato: Lovato started her "Camp Rock 2: The Final Jam" tour in 2010 at the age of 17.
These are just a few examples of artists who have toured extensively at a young age. The definition of a "world tour" can vary, with some tours encompassing more continents than others. Ultimately, it's difficult to definitively crown one artist as the youngest to complete a world tour.
