Holly Madison has had ferrets painted on her fingernails.

The former Playboy model has two of the rodents and regards them as her "kids" who she likes to show off to people, so decided to get a manicure in tribute to her pets.

She told America's Star magazine: "I have two ferrets and I love them. I think they're so cute.

"I'm getting something crazy on my nails, I just wanted to go totally crazy.

"I love to show people pictures of my ferrets on my phone like they're my kids, so I might as well put them on my hands."

Holly got the ferrets last year, with the first being a gift from a friend and the second adopted from a rescue shelter, and she loves lavishing them with presents - they even have an outdoor entertainment area.

She said: "I have a little house with air conditioning for them."

The 31-year-old blonde beauty is still in touch with her former 'Girls Next Door' co-stars Bridget Marquardt and Kendra Wilkinson - and fellow ex-girlfriends of Hugh Hefner - and though she is close to Kendra, she loves finding out what her pal and her family are up to by watching her friend's reality TV show.

She said: "I love seeing what Kendra is doing. I usually hear what she's up to from her beforehand but seeing it play out is always a lot of fun.

"I think I've been on every season of 'Kendra'. I'm losing track. It goes by so fast. I was on it for her baby shower, so fairly regularly, every now again.

"Kendra and Hank are such a good combination; they made such an adorable and unique-looking baby. Hank is a really good guy for her."
