The HIGH SCHOOL MUSICAL franchise has been rocked by a new nude scandal - teenage star VANESSA HUDGENS reportedly once took naked photos of herself to tease co-star and boyfriend Zac Efron. The 19-year-old's candid mirror-image shots were intended for Hairspray star Efron's eyes only, but U.S. reports suggest the photos are about to start circulating in cyberspace after a third party got hold of them. A source, who claims to have seen the suggestive snapshots, tells American tabloid the National Enquirer, "Shooting into a mirror with her camera phone, she took photos of herself naked except for a gold chain around her waist."
