Holly Madison is one hot mom-to-be!

The former Playboy Playmate and Girls Next Door star broke news to Us Weekly last week that she is expecting her first child with boyfriend Pasquale Rotella, 38.

Now 13 weeks along, Madison is showing off her pregnant bikini bod. The 33-year-old mom-to-be stepped out in a hot pink bikini Wednesday in Laguna Beach, California. Looking glammed up with her long blonde hair and full makeup, Madison flaunted her small baby bump as she stepped outside to catch some rays. 

"I've always wanted to be a mom," Madison, 33, told Us. "But I thought it would take longer!"

But her boyfriend of nine months is thrilled. "I texted him from the doctor's office! I knew he'd be so happy," the star of Las Vegas burlesque revue, Peepshow, explained of how she shared the news to Rotella. "We want to have six kids.
