Liam Hemsworth is "much happier" after splitting from Miley Cyrus.

The Hunger Games: Catching Fire star, who broke up with the "Wrecking Ball" singer in September, says he's in a better place now and is moving on. "These days I feel like I'm more centered and grounded than I've ever been," the 23-year-old told The Associated Press.

The actor, who met Miley in 2010 on the set of their film The Last Song, admits he's gone through a lot since moving to Hollywood from his native Australia five years ago: "I've learned so much. The first few years in L.A. were really tough and scary, but I had to figure things out for myself."

And that meant learning to deal with all the media attention after his engagement to 20-year-old Miley, whose controversial comeback and twerking antics were said to be the reason behind their breakup. "What I always keep in mind is that I know what the truth is and that's all that matters. I know I'm a good person," Liam said.

After admitting he's not seeing anyone special, he credits surfing and kickboxing with helping him to escape the pressure and says his co-star Jennifer Lawrence has helped him find balance in his life. "For a few years I went down a path where I forgot to be in the moment and enjoy the moment. But being around someone like Jen, who is so honest and laughs all day long, I am forced to be in the right now. I'm much happier," he said.
