Online reports that High School Musical
star Ashley Tisdale has been diagnosed HIV positive are "completely untrue," her rep, Scott Appel, tells PEOPLE.
Several Internet posts Thursday said the actress/singer may have contracted the disease from her rhinoplasty procedure
last year. By Friday the rumor mill kicked into overdrive causing some panicked fans to post YouTube videos to "Pray for Ashley."
Another Internet site posted what it claimed was a statement from Cedars-Sinai Medical Center in Los Angeles.
But Cedars-Sinai spokesperson Simi Singer tells PEOPLE: "We absolutely did not issue a release."
Tisdale, 22, is currently in Salt Lake City filming High School Musical 3.Like this story? Click on the Yahoo Buzz! button below to Buzz it up!
