Holly Madison admits to being 'suicidal' while living at Playboy mansion

In a new memoir, Hugh Hefner's former companion Holly Madison has admitted to being suicidal while living at the Playboy Mansion.

The promotional material for the memoir 'Down the Rabbit Hole' states that life inside the notorious mansion wasn't a dream at all and quickly became the 35-year-old Playboy model's nightmare, the CNN reported.

It added that after losing her identity, her sense of self-worth and her hope for the future, the 'Girls Next Door' star found herself sitting alone in a bathtub contemplating suicide.

Madison, who is now married to promoter Pasquale Rotella and has a young daughter, also details stories of backstabbing Bunnies and very strict house rules in her memoir, which is due out in June.

Madison added that she is excited to finally share her story and what she has learned from her personal experiences both inside and outside of the Playboy Mansion.

She continued that she thinks her stories will surprise people and she is looking forward to lifting the veil of mystique and clearing up the misconceptions so often associated with her life.
