"This is the most amazing sweet 16 that a girl could have!" The Hannah Montana star said about the bash, where the birthday girl also performed a brief, four-song concert for the crowd.

"My parents shut down Disneyland for me, so I'm good for a while."

In addition to the thousands of fans, who each paid $250 for the opportunity to party with the soon-to-be 16-year-old, a host of big-name celebrities, including  American Idol runner-up David Archuleta, Tyra Banks, Cindy Crawford, Steve Carell and many others, were on hand for the event.

More important for Miley than all the celebrity guests was her boyfriend, 20-year-old Justin Gaston, who not only showed up for the party, but also joined his gal-pal's dad, Billy Ray Cyrus and sister Brandi, onstage to sing Billy Ray's hit, "Achy Breaky Heart."
