"I've sat by in silence for a long time now about the way women's bodies are constantly scrutinized," the 28-year-old actress writes on her Web site. "To set the record straight, I'm not upset for me, but for all the girls out there that are struggling with their body image."

The photos show Hewitt, with a bit of cellulite, on a Hawai'i beach with her new fiance, Scottish actor Ross McCall.

Several sites posted the shots, along with some less-than-complimentary comments. TMZ.com, for example, said, "We know what you ate this summer, Love — everything!"

"A size 2 is not fat! Nor will it ever be," Hewitt responded in a post Thursday. "And being a size 0 doesn't make you beautiful."

"What I should be doing is celebrating some of the best days of my life and my engagement to the man of my dreams, instead of having to deal with photographers taking invasive pictures from bad angles," says the star of TV's "Ghost Whisperer" and the film "I Know What You Did Last Summer."

"To all girls with butts, boobs, hips and a waist," she wrote, "put on a bikini — put it on and stay strong."
