Liam Hemsworth and Miley Cyrus have been dating for 10 years, briefly splitting up in 2014.
In one of the pictures, the duo can be seen embracing each other, with a wedding ring visible on the 28-year-old actor's finger. It was a small ceremony attended by close friends and family, according to reports.
Hemsworth also shared the same photo, writing, "My love".
After shocking everyone with a secret wedding this weekend, Miley Cyrus seemingly confirmed her newlywed status on social media.
Cyrus, who found fame after starring in Disney's television series Hannah Montana, also shared a video filmed by producer Mark Ronson whistling Here Comes The Bride.
Among the guests at the wedding were the couple's siblings Noah and Brandi Cyrus and Chris and Luke Hemsworth. By October 2016, Cyrus announced on The Ellen DeGeneres Show how she and Hemsworth were engaged again.
Last year, Cyrus said she is gender-neutral after referring to herself as "a gender-neutral, sexually fluid person" in an interview with Billboard magazine. Cyrus' mom, Tish Cyrus, and dad, Billy Ray Cyrus, were in attendance.
Hemsworth, in turn, claimed to Men's Fitness in 2015 that being with Cyrus was "an important part of my life".
