With stars on shows like "90210" getting skinnier at a controversial rate, Valerie Bertinelli is getting candid with ET about the pressure to be thin in Hollywood!

"I think we're all sick of trying to be a 'Skinny Minnie,'" says the Jenny Craig spokesperson. "Not all of us are born that way. A lot of us have to struggle, and we don't want to struggle anymore. We just want to be happy in the size that we're in, and the food that we're eating, and that's what happens when you eat Jenny."

After shedding 40 pounds, Valerie tells ET she's reached her ideal size, and the goal is all about how you feel, not who you compare yourself to.

"It doesn't matter what's on the scale, or what jean size you're wearing -- but how do you feel?" she says. "Are you comfortable in your body? What's your ideal size? What does that mean to you?"

With the Jenny Craig Ideal Size Challenge, Jenny is holding a photo and video contest to find a co-star to appear with Valerie in her fun-filled commercials, but the former "One Day at a Time" star is clearly having a tough time picking just one person!

"I would let everybody win if it was up to me," she says. "They all sound like me -- where I was a year ago, and where I am today. I don't know how anyone's going to pick. I just don't want to pick because they're all fabulous."
