The 20 year old was left shame-faced again this month (Aug09) after pictures - allegedly showing the star posing topless - were leaked on the internet.
She faced further humiliation at the Teen Choice Awards in Los Angeles on Sunday (09Aug09) when comic Dane Cook took the stage and told the whole audience that Hudgens needed to "keep" her clothes on.
Despite fans booing the funnyman at the event in support of the star, online forums have been buzzing with teenage critics of Hudgens' antics.
And her co-stars in latest movie Bandslam are tired of seeing their pal slated online - insisting she is a "sweet girl" who has done nothing wrong.
Actor Charlie Saxton says, "It's so totally uncool. It's like, come on. Give me a break.
"She's such a sweet person, such a nice girl. She really doesn't deserve all the negativity that she's getting.
And fellow actress Aly Michalka believes the negative comments stem from jealousy about her relationship with hunk Efron.
She explains, "I think that it's about people being hard on people just to be hard on them. It's hard to avoid that sometimes... I think it really is based on that and I think maybe her being with Zac (Efron).
Hudgens faced a similar scandal in 2007 when pictures of her posing provocatively both nude and in lingerie appeared online - forcing the Disney star to issue a public apology.
