She's not that naive and innocent though. Vanessa Hudgens reveals the dark side of her good-girl image. Words are mounting that the High School Musical (HSM) actress is pretty nervous as her steamy photos are about to make their way to public.

The steamy shots, allegedly sent to co-star boyfriend Zac Efron, reportedly show her "naked except for a gold chain around her waist," a source in the know revealed. "She also photographed herself naked in the bathtub, blowing kisses and sensuously pulling down her bikini bottom. And she took a photo on the beach of her wearing a Zac button pinned to the top of her swimsuit."

Unfortunately for Vanessa that those pictures have been obtained by a third party who soon about to post it on the internet.

"She took some suggestive shots of herself in the buff as a surprise for Zac," an insider of the "High School Musical" franchise said. "Vanessa is only 19-years-old so she had no idea how her flirtatious act could threaten the future of the show. It's a kid's show. Naked pictures of one of the stars would be catastrophic."

So, will the naked pictures be a career jeopardy or career boosting for the young actress? You'll be the judge.
