Vanessa Hudgens has become famous for her wholesome look and sweet singing voice, but a nude photo that has hit the Internet is definitely striking a low note for the "High School Musical" star.

"It is unfortunate that this has become public," an unnamed rep for the 18-year-old singer/actress said in a statement released to Us Weekly.

The picture appears to have been taken in a bedroom or on-set production trailer. Standing and pulling her hair back with one hand, a smiling Hudgens shares the frame with a bed, a wooden dresser -- and nothing else.

"This was a photo which was taken privately," Hudgens' representative said in the statement, confirming the authenticity of the first leaked picture.

The release of the image could signal trouble for Hudgens, who is currently in negotiations for a third "High School Musical" film (see [article id="1564571"]" 'High School Musical 3' Won't Be Haunted -- But It's Still Headed For Big Screen"[/article]). Parent company Walt Disney, which is known for its wholesome image, had some well-documented issues with Melissa Joan Hart in 1999 when the "Sabrina" star posed in nothing more than a bedsheet for Maxim magazine, under the headline "Your Favorite Witch Without a Stitch."

With that kind of history, "High School Musical" fans are already wondering if Zac Efron's gal has bared too much of herself during this solo number.
