Holly Madison is so ecstatic over motherhood that she's thumbing her nose at the haters who have criticized her baby name selection.

The new mom, who welcomed daughter Rainbow Aurora on March 5, dismissed her critics in a brief but succinct blog post she published over the weekend.

"There are a lot of smug haters out there who bag on my choice of a name, but I don’t care about what they think," wrote the 33-year-old, who welcomed the baby with her party promoter beau, Pasquale Rotella. "I want my daughter to be proud of who she is and learn to speak up and stand up for herself at a young age. I spent most of my life being a people-pleaser who worried about what other people thought or thought was cool and I don’t want that for her."

Madison went on to talk about how she picked the name Rainbow, noting that she didn't invent it. It was actually the name of a girl she knew when she was growing up.

"I have always loved the name Rainbow," shared Madison, who was born Hollin Sue Cullen. "There was a girl in my school a few years younger than me named Rainbow and I was so envious of her name because it was so pretty and unusual. She was a perfectly normal, well-adjusted, sporty girl, by the way, so I’m not worried about my daughter being 'traumatized' by having an unusual name."

The reality TV star concluded by writing, "I couldn’t be more blessed to have such a perfect daughter and have never been happier than I am now!"
