After giving birth to her first child on Tuesday, former Playmate Holly Madison finally landed on a name - Rainbow Aurora Rotella.

According to E! News, Madison, 33, said, "I wanted to give my daughter a unique name."

However, her daughter won't be the first girl to have been named Rainbow. Madison told the publication that she knew a girl named Rainbow when she was growing up. She recalls being envious of the name because she thought it was "so pretty and unique."

The former Peepshow frontrunner's daughter weighed in at 7 pounds 2 ounces when she entered the world on March 5.

Madison told InTouch the day her daughter was born, "I've never been more in love than I am today as, after months of waiting, I finally was able to hold my daughter for the first time."

Her boyfriend, Pasquale Rotella, 38, added that he and Madison were looking forward to spending quiet time with their new daughter. "I'm truly the luckiest man in the world," he told the magazine.

Madison starred in the series The Girls Next Door, which premiered in 2005 and dated Hugh Hefner from 2006 to 2008. She then starred in her own series Holly's World in 2010.
