When fighting a highly publicized custody battle with the modeling industry's reigning Good Girl Next Door, it's probably not the smartest move to give Al Goldstein and Larry Flynt a run for their money as dirtiest old man. But that's just what pervy adulterer Peter Cook did yesterday while testifying against original Uptown Girl Christie Brinkley. Providing us with a handy preview of Rob Lowe's inevitable court date fighting for his straight-laced honor, the hottie architect let loose a series of confessions involving adorably vintage tales of web cam masturbation, office sex, and hush money hidden behind paintings. Read on for the sordid admissions that caused Cook to reach for a hankie and cry jurors a river.

As TMZ reports, Cook "broke down crying after getting grilled on the stand...[and] admitted he masturbated in front of a web cam and frequented escort, porn and swinger sites, all while married to Brinkley." Cook also unleashed a salty waterfall of tears while 'fessing up to a $300k extortion scam gone awry, in which he gradually donated large sums of money to his then-18-year old mistress' Get Rich By Boinking Celebrities fundraiser by stashing cash under rocks and other office decor. But the most grim allegation came from Brinkley's lawyer, who claims her prepubescent son Jack (from an earlier marriage) stumbled across nudie pics of "young girls" on Cook's computer. Which must have surely aided the kid's expected progression towards following Billy Joel on the path towards future wives young enough to be his daughter.
