The former `Girls Next Door` star is expecting her first child with Pasquale Rotella next March and she is already planning a "whole tribe" of siblings for the new arrival.
She said: "We want to get married after the baby is born, definitely. We want a small and personal wedding. But it won`t happen until next year at least.
"We want six kids. We want a big family - a whole tribe!"
Holly - who is expecting a baby girl - recently admitted it had taken some adjusting to get used to her pregnant shape.
She said: "I`m just getting used to this whole new body. It can be very awkward. My boobs haven`t really gotten bigger but I just recently started having back pain, which sucks because I can`t take anything for it.
"I`ve gained about 19 pounds which is pretty normal. I feel good - like I`m healthy and really where I`m supposed to be."
