The actor has posted a message addressing the matter on Instagram.
"Hi all Just a quick note to say that Miley and I have recently separated and I wish her nothing but health and happiness going forward," he wrote. "This is a private matter and I have not made, nor will I be making, any comments to any journalists or media outlets. Any reported quotes attributed to me are false. Peace and Love."
News that the stars were going their separate ways after less than a year of marriage broke over the weekend.
“Liam and Miley have agreed to separate at this time,” Cyrus’ rep told TODAY.
“Ever-evolving, changing as partners and individuals, they have decided this is what’s best while they both focus on themselves and careers. They still remain dedicated parents to all of their animals they share while lovingly taking this time apart. Please respect their process and privacy.”
Cyrus continued to focus on the theme of evolving when she posted a message on Instagram the day after news of the split broke.
“Don’t fight evolution, because you will never win,” she wrote, in part.
Cyrus, 26, and Hemsworth, 29, met in 2009 on the set of the movie "The Last Song." They dated on and off for three years, before the actor popped the question in 2012. They would call off the engagement a year later before ultimately renewing their relationship in 2015.
The couple revealed last December they had gotten married.
"I feel really happy, and really fortunate to be with such a great person," Hemsworth told TODAY's Willie Geist in February. "We've been through so much together over the last 10 years, so it felt like it was time."
"We’re getting handed a piece-of-s--- planet, and I refuse to hand that down to my child," she told Elle. "Until I feel like my kid would live on an earth with fish in the water, I’m not bringing in another person to deal with that."
Editor's note: An earlier version of this story contained quotes from the Daily Mail Australia that Hemsworth has subsequently denied.
