Vanessa Hudgens is Fat

She has always been seen as one of Hollywood's most petite actresses.

But High School Musical star Vanessa Hudgens appears to have developed some extra curves in recent months - especially in the chest area.

The 22-year-old showed off her more voluptuous appearance as she filmed scenes for a new film, Journey 2: The Mysterious Island, on the beach in Hawaii yesterday.

The actress has clearly undergone a figure transformation for the film - probably with the help of a heavily padded bra.

At the end of August she was seen looking much flatter up top as she strolled out of a grocery store in Los Angeles.

At only 5'4'', drastic changes in her appearance are more apparent.

In a pair of khaki shorts and a burgundy coloured vest top the slim star climbed over rocks and sat on the sand while the cameras rolled.

She also had to protect herself with an enormous umbrella when a sudden rain shower swept through the set.

The actress is filming the movie alongside Dwayne 'The Rock' Johnson, Kristin Davis and Josh Hutcherson on the tropical island before heading to New York and then Wilmington in North Carolina to finish up.

The movie follows Sean Anderson, played by Josh Hutcherson, who partners up with his mother's boyfriend (The Rock), to find his grandmother who has gone missing on a mythical island. It is due out in September next year.

Just yesterday the star was nominated for the Favourite Movie Star Award (under 25) at the People's Choice awards.

She will actually be competing against her long term boyfriend Zac Efron, as well as Kristen Stewart, Robert Pattinson and Emma Watson in the same category.
