Steve Granitz/Getty ImagesThe 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 celebrate her big day—which, technically, isn't until November 23—were Jennifer Love Hewitt, Cameron Mathison, Tyra Banks, Christian de la Fuente, Julianne and Derek Hough, David Archuleta, fellow Disney starlet Demi Lovato, and Miley's rumored new beau, Justin Gaston.
A source tells E! News that the guest of honor, who glowed in a shiny silver and gold dress 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 her BFF Mandy Jiroux and her 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.
