“High School Musical” star Vanessa Hudgens gets very dirty on the set of her new movie “Journey 2: The Mysterious Island,” an action-adventure flick now filming in Hawaii. New photos show she’s definitely graduated from high school.

Dwayne ‘The Rock’ Johnson, Kristin Davis and Josh Hutcherson are also in the film. Luis Guzmán is playing her father and Brad Peyton is directing.

Hudgens, 22, looked decidedly bustier in the filmed scenes, thanks either to a breast enhancement or some strategic padding in her push up bra.

In the photos she romps on a beach in khaki short-shorts and a tight fitting burgundy top.

She climbed over rocks (it’s action-adventure, remember) and rolled on the beach.

The movie, a sequel to “Journey to the Center of the Earth,” is loosely based on Jules Verne’s book “The Mysterious Island.”

Hutcherson’s and Johnson’s characters are forced to go to a mythical and monstrous island to find Hutcherson’s missing grandfather played by Michael Caine.

The movie is currently shooting in Hawaii and will film in New York and North Carolina before wrapping. It’s due out next year.

Hudgens was just nominated for the Favorite Movie Star Award (under 25) at the People’s Choice awards.

She will go up against her boyfriend Zac Efron,  Kristen Stewart, Robert Pattinson and Emma Watson in the category.
