Vanessa Hudgens 'embarrassed' by private pic

What time is it? Time for Vanessa Hudgens to do some damage control.

A nude photo of the "High School Musical 2" star has been circulating the Internet, which has prompted the young actress to address her actions.

"I want to apologize to my fans, whose support and trust means the world to me," says Hudgens in a statement to "Extra" on Friday, Sept. 7. "I am embarrassed over this situation and regret having ever taken these photos. I am thankful for the support of my family and friends."

The photo was first reported by The National Enquirer and has been splashed all over the Internet on blogs such as PerezHilton.com. Hudgens, 18, is seen fully nude and standing, facing the camera in what appears to be a private bedroom. Online speculation wondered if the photo was faked, but TMZ.com confirmed on Thursday that it's authentic.

"This was a photo which was taken privately," says Hudgens' rep. "It is a personal matter and it is unfortunate that this has become public."

Hudgens is best known for her starring role as the plucky Gabriella in the Disney Channel "High School Musical" franchises and has guest starred on the network's various other shows. The premiere of "HSM 2" on Aug. 17 broke numerous records, including becoming the most-watched basic cable telecast ever, drawing in an estimated 17.2 million viewers. The film's soundtrack, which has been the nation's top-selling album for the past three week, includes songs such as "What Time Is It?," "Gotta Go," "I Don't Dance" and "The Music in You."

Hudgens is reportedly dating her "HSM" costar Zac Efron, who is also featured in the film "Hairspray." She also released her solo debut album "V" in 2006.
