Ashley Tisdale Almost Froze Shooting Hot Maxim Photos

The Scary Movie V actress, 27, says her sultry photos – including the cover shot – in the May issue of Maxim are a bit deceiving. What looks like summer was anything but.
"It was freezing. It was not really that fun," she told PEOPLE Thursday at the Scary Movie V premiere in Los Angeles. "I was in Malibu, in the wintertime, with nothing on."
Oh, and it gets worse. "I was sick with bronchitis," she adds. "Like, on antibiotics."
Donning a leather jacket – and not much else! – in the chilly winter wind might have been against doctor's orders. But Tisdale says it was worth it in the end.
"I was freezing, but I had so much fun doing it," she says. "In those moments, the adrenaline pops in, and you're like, 'Whooo!' "
