The 27-year-old Australian actor shared a new picture with Cyrus Sunday after rekindling his romance with the 24-year-old American singer last year.
"My little angel and I," he captioned the snapshot for his 8.9 million Instagram followers.
Hemsworth and Cyrus reconciled in January 2016 after ending their engagement in 2013. The singer gave her past self advice about her relationship with Hemsworth in an interview with SiriusXM's Hits 1 in Hollywood in May.
"I think, know that everything is happening for the right reason," she advised. "I knew that when we weren't together the first time. I didn't know if that was the end of it or knew if we'd be back together again, but knew that wherever I was going was on the right path."
"People that break up and get back together, I think that's awesome because you know it's true, but also you get time to be yourself. You get time to grow up," the star added.
Cyrus' mom, Tish Cyrus, told Mario Lopez on On with Mario in June that Cyrus and Hemsworth aren't in a rush to get married.
"She is not eloping. She is not getting married," Tish said of her daughter. "She's so happy, and she's always like, 'I don't know why everybody wants us to get married. It's so perfect.'"
Hemsworth is known for playing Gale Hawthorne in the Hunger Games movies, and will next star in Isn't It Romantic with Priyanka Chopra. Cyrus last released the album Miley Cyrus & Her Dead Petz in 2015.
