The secretive love affair is so common that it's become a caricature of itself, yet it's still the fastest way to ruin a relationship. Here's our list of the top five most clichéd affairs that men have.

Each one is so stereotypical, it's not even shocking -- unless you're the wronged woman. But c'mon, men, if you're gonna cheat, couldn't you at least be a little creative?

The Co-Worker
Many of us spend more time at work than at home, so it's natural to develop close relationships with colleagues. Some, ahem, closer than others. Just ask Brad Pitt -- his marriage with Jennifer Aniston promptly ended after filming "Mr. and Mrs. Smith" with the most irresistible woman alive, Angelina Jolie. Though to be fair, we'd all leave our lovers for Angelina.

The Pro
Picking up a hookah or ordering a call girl seems like the most foolproof way to keep a rendezvous under wraps. They're cooperative, eager to please, and paid for their confidentiality. Unfortunately, they're also more likely than the average Other Woman to be federally wiretapped. Such was the fatal flaw that revealed New York governor Eliot Spitzer's very expensive affair with high-class call girl Ashley Alexandra Dupre.

The Assistant
Secretaries, receptionists and personal assistants have always been first-class, grade A meat for sleazeball big wigs to indulge in at their convenience. In movies, they're portrayed as young, vivacious and always keen on pleasing their boss ... in every way. A prime example of this in real life is Peter Cook, who hooked up with a 19-year-old assistant at his architecture firm after almost 10 years of marriage to supermodel Christie Brinkley. Yes, Christie Brinkley, Sports Illustrated swimsuit goddess. Duh.

The Nanny
These sexy temptresses can even bust up perfect households -- take Jude Law and Sienna Miller. Daisy Wright tucked in the kids, tended to Jude and went to the papers. The nerve of those Mary Poppins tramps!

The Other Man
Cheating is somehow even worse when it's with someone who has matching anatomy. Questions flurry the mind: Has he always been gay? Did I turn him gay? Is it because I'm an unattractive heifer?! We could only imagine what went through Dina McGreevey's head when former New Jersey governor Jim McGreevey publicly acknowledged his affair with his security aide. A courageous move, yes, but a wife's worst nightmare.

Tell us! Which brand of clichéd cuckoldry did we leave off the list? Has a guy ever cheated on you with one of these stereotypical women?
