The whole world may be buzzing today about the impending royal baby, but there are plenty other celebs expecting -- including the royally pregnant Holly Madison!
The former Playboy Playmate, 32, showed off her growing baby belly this weekend at The Animal Foundation's Shelter Elves kick off celebration at the Mandalay Bay Casino, Las Vegas.
The event celebrated the 20 year anniversary of the House of Blues, with proceeds benefitting The Animal Foundation -- a non-profit organization operating Nevada’s largest animal shelter (Lied Animal Shelter) and animal adoption center.
The self-proclaimed animal lover, who has participated in PETA's "I'd Rather Go Naked Than Wear Fur" campaign, glowed in a sapphire blue mini dress, with glittery gold heels. She's expecting her first child with boyfriend Pasquale Rotella in March, and pregnancy looks good on her!
