The couple are reported to have Wednesday in a small ceremony in Tennessee.
The couple confirmed their wedding by sharing fabulous pictures from the ceremony on social media.
Cyrus captioned yet another photo, referring to the number of years since they first fell in love on the set of the 2010 drama The Last Song.
When recently asked by radio DJ Howard Stern if she calls Hemsworth her boyfriend or fiance, the 26-year-old said she refers to him as her "survival partner". The pair dated for years before he proposed in 2012, but the two ended their engagement and broke up a year later.
The once on-again off-again couple, who reconnected in 2015, exchanged vows in an intimate affair at their home. The wedding is reported to have taken place at another property owned by Cyrus, in Franklin, Tennessee. He captioned the photo: "My love", with a heart emoji.More news: Corbyn denies calling May 'stupid woman'

The "Party in the USA" hitmaker also shared a video of herself and her husband dancing to her friend and collaborator Mark Ronson's song "Uptown Funk" on her Instagram story.
"Special here comes the bride cyrus/hemsworth remix for 2019". Miley's family was also in attendance, including her mom, Tish, and sisters Noah and Brandi.
Last month, the singer tweeted the pair made it out safely after their home was ravaged by wild fires in California.
