Los Angeles, June 12 (IANS): Former Playboy model Holly Madison, who has a two-year-old daughter Rainbow with her husband Pasquale Rotella, has revealed that she is hoping to add to her brood.

She is planning it after she finishes the promotional tour for her new book "Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny".

"Hopefully soon. Hopefully after the book tour," she told people.com upon being asked when she was planning on having a second child.

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

She said: "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 confessed she contemplated suicide while living in the Playboy mansion with publisher Hugh Hefner 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."
