The Princess Diana and Jeon Jungkook reincarnation theory is a viral internet legend that connects the late Princess of Wales with the youngest member of BTS. The theory centers on the specific timeline of their lives: Princess Diana tragically passed away on August 31, 1997, and Jungkook was born less than 24 hours later on September 1, 1997. Fans on TikTok and Twitter popularized the meme by creating aesthetic collages that compare the two figures' similar facial expressions, fashion sense, and public personas. While mostly lighthearted and tongue-in-cheek, the meme highlights the BTS Army's dedication to lore and their perception of Jungkook as a 'royal' figure in the world of modern pop culture.
