Holly Madison Names Her Newborn Daughter Rainbow

And we thought Apple was a crazy name!

Holly Madison gave birth to a baby girl on Tuesday, and she was still undecided on a name until today, when she revealed the chosen moniker was Rainbow Aurora Rotella!

How on Earth did the Playboy model and her beau Pasquale Rotella come up with that?!

"I wanted to give my daughter a unique name. 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!" she told E! News.

Welcome to the world Rainbow!
