Born as Destiny Hope Cyrus, the star of Disney's hit show "Hannah Montana" is best known by her beloved fans as "Miley". But now she has officially and legally changed her name to Miley Ray Cyrus, to reflect her nickname as well as honor her father.

The name Miley stems from a childhood nickname, where her family always called her "Smiley." Soon, that became "Miley", which obviously stuck and is what most of us know her by. Miley chose the new middle name "Ray" in honor of her dad, Billy Ray Cyrus.
