"My Valentine every single day," she began.

In another sweet pic, she wrote, "Thank you for always bending down to hug me ... I promise I will always meet you in the middle on my tippiest toes! I love you Valentine! @liamhemsworth."
Here's one with the cake.
And just a few more for good measure.
Cyrus and Hemsworth married in December 2018 after knowing each other for 10 years.
Reports that the couple got married started to roll in after surfer Conrad Carr posted a video to his Instagram story of the Hemsworth brothers taking what looks to be a shot together. In the background you can see "Mr. and Mrs." balloons.
Later, the singer posted a slew of pics and videos, along with her parents, confirming the big news.
Hemsworth, 29, and Cyrus, 26, met on the film "The Last Song" and dated for three years before getting engaged for the first time in 2012. They broke things off the next year but got back together in 2015. They got engaged again in 2016.
