Miley Cyrus wants to change her real name Destiny Hope Cyrus to Miley Ray Cyrus. The young sensation has previously said her adopted first name comes from a nickname her father called her as a baby "Smiley Miley”. Parents Billy Ray and Leticia Cyrus filed the papers Friday (March 14) in Los Angeles Superior Court on their daughter's behalf, reports claim. The petition reads that Cyrus wants to "make her commonly used name the same as her legal name." The 15-year-old Montana star first commented about her legally changing in January. Miley and her dad will be hosting the Country Music Television ceremony together at Nashville's Belmont University on April 14.
