Miley Cyrus is in the mood to celebrate.

On Monday, the "Mother's Daughter" singer took to Instagram to commemorate the 3rd anniversary of her song "Malibu," which was inspired by her rekindled romance with ex Liam Hemsworth. In the 2017 song, Cyrus details getting back together with The Hunger Games star in 2015 and picking up where they left off in Malibu, which is where they lived together before their 2019 divorce.
