What was Hollywood’s harest working 16-year-old up to today?

Working, of course!

Showing off her grill full of pearly whites, Miley Cyrus was seen leaving the set of The Last Song on the beach at Tybee Island, GA this afternoon (June 29) following a long day of filming.

Between takes, Miley could be seen thumbing through the pages of Ellen Hopkins’ Identical, a tale about two indentical twins who are seemingly living the perfect All-American life, but in reality, they have their own dark secret.

Meanwhile, some MC fans waited more than three hours in the sun to catch a glimpse of the teen Disney sensation. But for most of her fans it was worth the wait.

“It’s a big deal because Miley’s so famous and Savannah is such a small town that I think everyone’s really excited for Miley to be here,” a tweenage uber fan tells local media. “We saw her but we saw her back and we’ve been waiting for an hour.” Adds the mother of another: “We just came and sat and waited for two hours. It was worth it because she loves Miley Cyrus and was worth it for her so it was worth it for me.”
