They say you never forget your first love.
Liam Hemsworth says he still has feelings for his ex-fiancee, Miley Cyrus -- whom he began dating after meeting on the set of their 2010 romantic film, The Last Song, before ending their engagement in September 2013 -- in a new interview with Men's Fitness.
"I mean, look -- we were together five years, so I don't think those feelings will ever change," Liam, 25, explains. "And that’s good because that proves to me that it was real. It wasn't just a fling. It really was an important part of my life and always will be. She's a free spirit. I think she'll always surprise people with what she does, but she's not a malicious person in any way. She's a young girl who wants to do what she wants to do."
The Hunger Games star says it was definitely love when it came to his relationship with the controversial 22-year-old singer.

"You fall in love with who you fall in love with; you can never choose," Liam says when asked by the magazine if he felt like he "dodged a bullet" given his ex's now much racier reputation. "I guess some people just come with a little more baggage."
In the candid new chat, Liam also admits to making plenty of mistakes in Hollywood.
"When you get thrown into this industry at a young age, you’re gonna say some stupid s**t. Absolutely," he says bluntly. "It’s impossible not to. Everyone does it. But you learn from it, and you learn from it quickly. You become a lot more mindful of what you say and how you say it."
Last December, Liam's older brother, 32-year-old Thor star Chris Hemsworth, said he had "no empathy" for Liam's less than ideal relationships.
"I've watched Liam do things I did at his age, like being in relationships he shouldn't be in, or being reckless just to prove a point," Chris told GQ. "And I had no empathy. My mom had to remind me I was the same way."
But these days, Liam is all about living a healthy lifestyle, and recently adopted a vegan diet. He says he was inspired by his Hunger Games co-star, longtime vegan Woody Harrelson, and has stuck to the strict diet for five months now.
"There are no negatives to eating like this," he says. "I feel nothing but positive, mentally and physically. I love it. I feel like it also has a kind of a domino effect on the rest of my life."

And getting into a relationship appears to be the last thing on his mind.
"It's tough to have a relationship in this industry, though not to the point where it makes me depressed," Liam explains. "I'm constantly working, and I love working. I don't feel like I’m missing out on anything at this point -- I feel like I'm focusing on the right things and prioritizing things in the right way, and I'm a healthy, happy person."
