In Touch can exclusively reveal that Playboy model Holly Madison, who once played house with Hugh Hefner, is hoping to start a family of her own!

I’ve started the adoption process … I really want to be a mommy,” Holly, 33, tells In Touch, on newsstands now. Holly, who admits she’s already planning nursery themes, tells In Touch the adoption mentoring service Hold My Hand is helping her in the lengthy process to secure a child from either Africa or South Korea.

Holly faults her trying schedule, which is jam-packed with events and theater roles, as the main reason she doesn’t have a bundle of joy just yet.

“I love performing in the theater, and you can’t really do that when you’re pregnant,” the former Girl Next Door star explains.
