Holly Madison picks a colorful name for her new baby girl Holly Madison chose a colorful name for her new baby girl with boyfriend Pasquale Rotella. Brace yourselves, this one's a doozy: Madison's baby moniker is Rainbow Aurora Rotella. Yes, you read that correctly, and it's OK if you're now craving some sort of exotic pasta dish. The "Girls Next Door" star, who is one of Hugh Hefner's ex-girlfriends, welcomed Rainbow Aurora on Tuesday at 11:59 a.m. She weighed in at 7 pounds, 2 ounces and went home to Madison's Alice in Wonderland-themed nursery. And here we thought her name might have been Alice. "I wanted to give my daughter a unique name," Madison, 33, told E! Growing up, there was a girl in my school named Rainbow and I was so envious of that name. I thought it was so pretty and unique! It's definitely better than Borealis, that's for sure. "I've been spending the last day or so learning how to be a mom," the new mom wrote on her blog Friday, taking time out to thank her fans for their support and post a new mommy and daddy photo while calling parenthood "the best project in the world! I never thought I would be so happy - especially on so little sleep! As for papa Pasquale, the promoter told In Touch that he had "never been more in love" than when Rainbow was born. I'm truly the luckiest man in the world," the 38-year-old said. Leprechauns, proceed in your jealousy, because this family probably won't let you anywhere near its pot o' gold.
