The 31-year-old reality TV star - who was in a relationship with Hugh Hefner until 2008 - explained she is keen to visit the Los Angeles home she shared with the 84-year-old magazine mogul and his other live-in girlfriends Kendra Wilkinson and Bridget Marquardt.
She said: "I'd love to stop by the mansion at some point in the day when no-one's there and visit Hef' and all the animals that live there. We talk on twitter sometimes.
"Kendra, Bridget and I are all far apart now but we speak all the time. Kendra's baby Hank just had his first birthday so we're trying to plan a trip to Disneyland."
Meanwhile, the blonde beauty has admitted she finds it "weird" her current roommate - who she shares a Las Vegas apartment with - is dating Hugh's 19-year-old son Marston because she has known him since he was a child.
Holly added to Perez Hilton: "My new roommate Claire is actually dating Hef's son Marston. I believe he's 19 now and Claire is 18 so that's so weird to me. He's in Los Angeles but he comes up to visit all the time, he's back and forth.
"It's weird to me because I've know Marston since he was like 12 and in my mind he's still like 12. We do have girl talk about it though."
