The ex-Playboy Bunny, who already has a two-year-old daughter Rainbow with her husband Pasquale Rotella, has confessed the couple are hoping to add to their brood following the promotional tour for her new book 'Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny' which documents her time as one of Hugh Hefner's live-in girlfriends.

Asked when she was planning on having a second child, the blonde beauty said: "Hopefully soon. Hopefully after the book tour."

The star also admitted she is worried her new addition won't be as well behaved as her first born.

She told PEOPLE: "Rainbow is awesome. I got off easy with her. She's a really good kid. Other people hate that she's so good."

Meanwhile, the 35-year-old model recently confessed she contemplated suicide while living in the Playboy mansion with the 89-year-old magazine boss and her fellow bunnies.

In her tell-all memoir she explains: "I just couldn't take my misery anymore. Of course my family would be devastated, but I rarely saw them enough for my absence to make a difference...

"Maybe it was the pot and the alcohol, but drowning myself seemed like the logical way to escape the ridiculous life I was leading."

She also insisted her life was not as "incredibly glamorous" as it seemed and was in fact very different to what she had expected when she first started out in the modelling industry.

She said: "Everyone thinks that the infamous metal gate was meant to keep people out. But I grew to feel it was meant to lock me in."
