Miley Cyrus apparently has enough to do keeping two names straight, let alone three.
The Hannah Montana star, who was born Destiny Hope Cyrus, is looking to make Miley Ray Cyrus—basically, what everyone knows her by—her legal name.
Parents Billy Ray and Leticia Cyrus filed the papers Friday in Los Angeles Superior Court on their daughter's behalf. The petition states that Cyrus wants to "make her commonly used name the same as her legal name."
They will also have to publish a public notice of her name change in order to make it official, per documents. (View the court filing.) Cyrus first talked about legally changing her name in January.
The 15-year-old TV and pop star has said her adopted first name originates from a nickname her dad gave her as a baby, "Smiley Miley."
And the rest is Disney Channel history.
Father and daughter are set to begin filming this spring on The Hannah Montana Movie, but first they'll host the 2008 CMT Awards in Nashville April 14.
The Cyruses also both appeared in the box office-topping 3-D concert film Hannah Montana/Miley Cyrus: Best of Both Worlds Concert Tour, the companion movie to Cyrus' frequently sold-out Best of Both Worlds tour, which had to tack on 14 more dates than originally planned to accommodate frenzied demand.
