Ashley Tisdale is well known for is wholesome image in High School Musical. But I guess she's a big girl now, and appeared on a nude photo shoot with Allure magazine's May issue. She is turning 26 this year so I think people are just used to her clean image.
Allure magazine's May issue also features Big Bang Theory's Kaley Cuoco, 25. She loved the photo shoot and is comfortable being naked. Other celebrities joined the issue includingBridget Moynahan 40 and Keri Hilson 28.
