Holly Madison gave birth to her first child, Rainbow Aurora, on March 5. Her E! special, Holly Has a Baby, will air Sunday at 9 p.m., following her from pregnancy to delivery.

Holly, 33, talked to On the Air With Ryan Seacrest about plans for Baby #2, although she reportedly wants to marry her baby daddy Pasquale Rotella first.

“I’d like to have a second baby by the time Rainbow is 2," Holly said. "So, next year we are going to start trying again. I want to have a big family. My boyfriend and I are aiming for like six…so, we’ll see how it goes."

The Girls Next Door alum was also asked if Hugh Hefner had sent her a baby gift or card or anything. Holly's response: "Not yet." Get on that, Hef!
