Before Miley Cyrus wrote a song about the single life that criticized her ex, Liam Hemsworth, she had a deep connection with him when they first met during auditions for the movie "The Last Song" in 2010. This film, based on a novel by Nicholas Sparks, is where their love story began.

Miley shared on TikTok that what made the movie special was that it captured the real-time blossoming of their love as two young people. She mentioned that the chemistry between them was undeniable, and this marked the start of a 10-year relationship. After completing the movie, they had an on-again, off-again relationship. Liam proposed to Miley in 2012, and they eventually married in December 2018 in Nashville, Tennessee. However, Liam filed for divorce in August of the following year, and their divorce was finalized in January 2020.

Miley's TikTok video is part of a series where the 30-year-old singer reflects on her past while promoting her new single "Used To Be Young." In the video, she also talked about how the movie project came about and how Liam eventually secured the role. She explained that in 2008, she had to do another feature film for Disney but wanted it to be separate from her "Hannah Montana" role. They conducted auditions for the part of Will, her boyfriend in the movie, and after narrowing it down from thousands to the final three candidates, Liam was among the top contenders.
