Holly Madison gave fans a peek at her ever-expanding baby bump this weekend as she attended a picnic in Las Vegas.

Madison's protruding belly was in full view as she stopped by the "Forever Home Family Picnic" event in Las Vegas' Freedom Park on Saturday. The picnic was meant to celebrate families who have rescued a shelter dog and provided it with a loving home.

The 32-year-old former "Girls Next Door" star wore a sweet yellow and purple dress as she smiled for photos and cradled her belly. Madison also talked with reporters about her pregnancy cravings.

"I crave blueberries all the time," she said. "I'm making blueberry muffins and blueberry smoothies, so knock on wood my cravings stay healthy."

And other than the cravings, Madison said she hasn't suffered many negative side effects that expectant mothers typically see.

"It's actually easier than I thought," Madison said. "I haven't had any of the crazy side effects ... No morning sickness or anything yet. So I've been lucky."

The child will be Madison's first, and the father is her boyfriend, party promoter Pasquale Rotella.

Madison recently dished to Us Magazine that she is planning a "very unusual" name for her new bundle of joy, adding that it will be "kind of Apple-ish," a reference to Gwyneth Paltrow's daughter Apple.

"I don't what to say what the names are, but I will say that they're very unusual," Madison said. "I don't like common names at all. If I've heard it before on somebody more than one time, then it's out."

The former Playboy model said she and her boyfriend know the sex of the baby, but they aren't prepared to make it public just yet.

"We're not telling anybody yet, but we found out and I'm really excited," she said. "I'm really excited about decorating the nursery, so we've already started buying some things there."
