sunglasses skinny Vanessa Hudgens shorts tank

Vanessa Hudgens and her little sister Stella went for a hike at Wilacre Park in Studio City on Monday, and after that the ladies continued their cardio workout at the gym. It may almost be November, but it's still super hot in the valley, so we don't blame the girls for wearing super short workout shorts! But what's with Vanessa's "Find The Beast" tee?

Over the weekend the Hudgens sisters hung with pal Ashley Tisdale at Universal Studios Halloween Horror Nights, and last night they went to a costume party dressed as sexy vampires:
