Photo: Ashley Tisdale poses nude

Ashley Tisdale has posed nude for a magazine.

The High School Musical actress did the sexy black and white shoot to show just how grown up she is.

“I’m 25, almost 26, but people think of me as much younger because I look young,” said Ashley.

“Being in this shoot was me saying: ‘I’m not just the young girl everybody thinks I am. I’m actually a woman.'”

Ashley actually brought her mum along to the shoot.

“I’ve always wanted to be sure my parents approve of what I do,” she told Allure magazine.

“Even with my tattoos, my mum went with me. The ‘believe’ tattoo is because my mum always told me to believe.”
