Life as one of the "Girls Next Door" wasn't as glamorous as it looked on TV.
Holly Madison, a former Playboy Bunny and star of The Girls Next Door, is set to publish a memoir later this year. Madison revealed the cover for the book, Down the Rabbit Hole, on Instagram this week:

In a press release, publisher Harper Collins said the book looks at some of Madison's darker moments.
"...What seemed like a fairytale life inside the Playboy Mansion-including A-list celebrity parties and her own #1-rated television show for four years-quickly devolved into an oppressive routine of strict rules, manipulation, and battles with ambitious, backstabbing bunnies," the release stated.
"Life inside the notorious Mansion wasn't a dream at all-and quickly became her nightmare. After losing her identity, her sense of self-worth, and her hope for the future, Holly found herself sitting alone in a bathtub contemplating suicide."
