In a new snap, she penned, "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!"
"L❤️VE YOU Valentine."
Miley then shared three colour photos of her beautiful wedding dress.
The silk gown was designed by Vivienne Westwood.
The newlyweds have been dating on and off since 2010, when they met on the set of the Nicholas Sparks adaptation The Last Song.
They said "I do" on December 23, 2018 at their home in Franklin, Tennessee.
