High School Musical actress Ashley Tisdale bares it all for a new photo shoot and RadarOnline.com has the sexy photo of the former teen star all-grown-up.

Appearing in Allure Magazine’s annual Nude Issue, Ashley Tisdale joins Bridget Moynahan, Keri Hilson, and Kaley Cuoco in the buff.

Ashley revealed that her decision to pose nude was less about showing off her killer shape and more about growing up.

"I'm 25, almost 26, but people think of me as much younger because I look young," she said.

"Being in this shoot was me saying, 'I'm not just the young girl everybody thinks I am. I'm actually a woman.'"

The actress also brought her mother along to the shoot, saying "I've always wanted to be sure my parents approve of what I do.”

"Even with my tattoos, my mom went with me. The 'believe' tattoo is because my mom always told me to believe."

Now, before you open this: My reasoning is that Ashley was never all that praised. She was constantly criticised for her singing and/or acting. It's not as often as it is now however. But, still. I know that she can be a decent actress (ala Sons of Anarchy, but the fans of that show flipped out over her being on it), but it seems to me that most people associate her with the High School Musical series and Zack and Cody.

But to me, I feel that this movie was the final nail in the coffin for her. She tried to do something "more mature" (in her own words and to breakaway from HSM and Zack and Cody, and wanted to for a long time. But did one more Sharpay movie for her fans), but I feel she will end up regretting it. Since this movie was released, a lot, and I mean A LOT of people I know have been hating and ragging on Ashley Tisdale, more so than ever. For example, I have noticed that the majority of her Facebook photos has at least one hate comment on it, and when a news article comes, people are taking digs at her and calling her a "has-been".

The Maxim shoot did not help either. Basically, this movie was so bad that it has completely damaged Ashley's reputation (Unlike Zac Efron, who is now fairly praised due to his breakaway from the HSM franchise and had his breakout role in something strong). Did her more bad than good, and now the majority of people despise her and I wouldn't be lying if I said that this movie probably played a huge factor into it.

And a lot of the people who enjoyed the Scary Movie franchise even hate her due to the obvious reasons (Ala she took over as lead in this one).

I sense that this movie was so bad that it pretty much has ruined Ashley's career. Not that it was good in the first place.
