The Happiest Place on Earth got a whole lot happier Sunday night, as Miley Cyrus celebrated her Sweet 16 at Disneyland with several celebs, friends and about 5,000 fans who paid $250 a pop to be there.
Among the famous faces in attendance to help the teen queen mark her big day—which, technically, isn't until Nov. 23—were Jennifer Love Hewitt, Cameron Mathison, Tyra Banks, Christián de la Fuente, Julianne and Derek Hough, David Archuleta, fellow Disney starlet (and frenemy) Demi Lovato, and Miley's rumored new beau, Justin Gaston, who performed Achy Break Heart with her dad, Billy Ray.
A source tells E! News that the guest of honor, who glowed in a shiny silver and gold dress from Kaufman Franco along with a pair of emerald-colored high heels, "was all smiles while signing autographs and taking pictures with fans. All of her friends and family were there, so she was really excited."
The Hannah Montana star was also joined on the "purple" carpet (her favorite color) before the big bash by BFF Mandy Jiroux and daddy Billy Ray, who revealed to E! News that he got his daughter a new puppy as a present.
No word on the pooch's name yet, but Pluto would certainly be apropos.
