Miley adopted her pit bull mix, Mary Jane, in 2012 and sadly lost the beloved dog to cancer in January 2021. Following her passing, Miley released a song in honour of MJ, called "Mary Jane 5EVR."
"I wrote this song in Malibu years ago on a piano in a house that no longer exists. About my dog Mary Jane who is also gone now. A lot has changed over time. Mostly me," Miley wrote in an Instagram caption. "Music is my medicine. This song revolves around loss & heartache. Which I am currently experiencing after Mary Jane's passing. MJ was a true queen. She wore her grace, dignity & kindness like a crown. She will never be forgotten and will forever be missed. To know her is to love her. It has been my honour being her mom and best friend."
In December 2017, Miley Cyrus visited tattoo artist Doctor Woo again to get another dog portrait, this time of Mary Jane, on her right elbow (pictured ahead).
