Well, it was fun while it lasted!  Miley Cyrus, the star of the huge television commercial success “Hannah Montana,” is now officially an adult, turning 18 years old today, November 23, 2010.  For better or worse, I can’t recall another television child actor in the last decade who has penetrated pop culture and the public consciousness more so than Miley Cyrus.

On Sunday at the American Music Awards, seemingly unhindered by her parents recent separation, Miley told Access Hollywood when asked about her birthday plans,“I’m going out dancing later — we rented out a space so all my friends can come.  Me and my mom actually have choreography for the night later — everyone loves when we dance in unison.”

She went on to say that she and Momager Tish Cyrus are known for playing Xbox 360’s dance video game, Kinect. “My mom, she beats me at that game!” Miley said. “She had 600,000 points yesterday, I had 300,000. She is such a good dancer — she really gets it.”

Miley: “There’s one [move] where you do like, the fist pump. You ‘Jersey Shore’ it for a second!  We got a bunch of moves going on. Everyone goes wild when me and my mom have choreography, so it’s going to be good.

In addition to Miley’s Momager Dance Routine, the now 18 year old  says that the entire month of November is a birthday celebration for her.  “I have a birthday month,” Miley tells Access Hollywood. “I do the whole month of November. Thanksgiving, cake – [it’s] all about me on Thanksgiving!”

Guests at her birthday celebration after the AMA’s on Sunday were Demi Moore, Rumer Willis, John Mayer, Kelly Osbourne, Kyle Massey and Ke$ha.

Here’s a look back at Miley’s transformation through the years:
