Before she was buying herself flowers, Liam Hemsworth was doing it for her.

Miley Cyrus recently reflected on her experience filming the 2010 movie The Last Song—during which she and Liam fell in love both onscreen and off—and revealed why she thinks her and Liam’s relationship in the movie worked so well.

“I think one of the elements that made that movie feel so special,” she shared in a Sept. 1 TikTok, “was it was watching two very young people fall in love with each other, which was happening in real time and real life.”

She continued, “So the chemistry was undeniable, and that was the beginning of a long, 10-year relationship.”

And indeed, Miley and Liam did take their chemistry offscreen, dating shortly after filming began on the Nicholas Sparks book adaptation, before becoming engaged in 2012. The pair were on-again, off-again for many years until they married in December 2018, before the Hunger Games actor filed for divorce in August 2019. Their split was finalized in January 2020.

In her TikTok, which is part of a series of videos reflecting on her past in honor of her new single “Used To Be Young,” the Hannah Montana alum also explained how The Last Song came to be—including how Liam ultimately landed the role.

“In 2008, I had to do another feature film for Disney,” she explained. “And I didn’t want it to be a part of Hannah Montana. Once we had written the screenplay, it was time to audition all the guys who would play Will, my boyfriend in the movie.”

“And we had gotten it down from thousands to the final three,” she noted, “and Liam was a part of those three.”

During their relationship, Miley and Liam lived together in Malibu, before the house tragically burned down in the California wildfires that tore through the state almost five years ago.

In a separate video for her “Used To Be Young” series, the 30-year-old reflected on the significance of both that house and that part of her life.

“The Meet Miley Cyrus record was really where I started writing my own songs as a solo artist,” Miley said in an Aug. 29 TikTok. “And so I was working with a producer in Malibu that lived in a house in Ramirez Canyon, which I would’ve never known 15 years later I would be living in that house, which would eventually burn down.”

She added, “That house had so much magic to it. It ended up really changing my life.”
