Hugh Hefner, 84, became engaged to Crystal Harris, 24, over the holidays. He may be a one-woman man now, but former Playmate Izabella St James revealed startling details about how he once treated his bevy of girlfriends in her memoir, excerpted in the Daily Mail.

Kendra Wilkinson has previously talked about each girl "hopping on" Hef for a one-minute ride, and another former Playmate, Jill Ann Spaulding, criticized his insistence on having unprotected sex.

Here are a few excerpts from Izabella's book, read more at the Daily Mail:

On the mess the dogs made in the house:

"They weren't house-trained and would just do their business on the bedroom carpet. Late at night, or in the early hours of the morning - if any of us visited Hef's bedroom - we'd almost always end up standing in dog mess. Everything in the Mansion felt old and stale, and Archie the house dog would regularly relieve himself on the hallway curtains, adding a powerful whiff of urine to the general scent of decay."

On the Playmates' weekly allowance:

"Every Friday morning we had to go to Hef's room, wait while he picked up all the dog poo off the carpet - and then ask for our allowance: a thousand dollars counted out in crisp hundred-dollar bills from a safe in one of his bookcases. We all hated this process. Hef would always use the occasion to bring up anything he wasn't happy about in the relationship. Most of the complaints were about the lack of harmony among the girlfriends - or your lack of sexual participation in the 'parties' he held in his bedroom."

On sex with Hef:

"I wanted to see if this experienced King of Sexdom knew anything the rest of us did not. But he just lay there like a dead fish. We often wondered why he did it at all. He must know deep down that it is just a show. But he is trying to live out this fantasy he has been selling to people since 1954."
