Several weeks back, Miley Cyrus said she was officially changing her name, and now it's done. She filed papers Friday in Los Angeles, according to TMZ.com, making Miley Ray Cyrus her legal name, in place of Destiny Hope Cyrus. Her mother, Leticia, accompanied her at the courthouse.

The teen phenom picked up the Miley nickname when she was a baby. Billy Ray appreciated her happy disposition and called her Smiley Miley.

She's got plenty of reasons to smile now, too. She's a mega-star, thanks to her role on "Hannah Montana," she got to sing with her dad on the country hit "Ready, Set, Don't Go," and she's also getting positive reviews from fellow artists, including her godmother, Dolly Parton, GAC's Artist of the Month for March.

"She's like a little Elvis," Dolly told AOL. "I think that she's gonna have a big career after that show is off the air, but I'm amazed at the talent that child has and the effect she has on people. And a lot of that ain't just Disney; a lot of that is Miley."
