Ashley Tisdale attended the "Scary Movie V" Los Angeles premiere wearing an unusual optical illusion dress. The actress showed off some skin in a slinky black gown, which included sheer, see-through panels on the legs and arms.

Tisdale has been revealing a lot of skin lately. In the May issue of Maxim magazine, she poses in a handful of provocative shots, including several in which she appears sans a bra.

So how does she stay so fit? "I work out with a trainer like three times a week, and then I'll do yoga or a hike and stuff like just during the week too, like a 45-minute session with my trainer," she told Starpulse.

But she does occasionally stray off her diet. "I definitely will be like watch what I eat, limit the carbs. But I work out and I eat whatever I like. I like pizza and I like ribs. I just feel like living a healthy lifestyle is just like working out...I tend to like healthier stuff anyway, I guess," she added.
