At this level your wife being a hot model means nothing. Dude... Someone has cheated on Halle Berry before. If that doesn't say anything I don't know what does.His wife is a model... Why a nookie?
Obviously for most of us non-multi-trillionaires, ungodly gorgeous chicks are a once in a life time thing and you don't exactly take it for granted or intentionally do anything to **** that up. For men like Tiger they are a dime a dozen. You can cheat on one ungodly hot goregous girl with another and if one finds out and gets mad and leaves, it's OK... you are still Tiger Woods. If you accidentally drop a 1,000 dollar bill on the ground it probably isn't worth your average hourly salary to go to the effort to stoop down and pick it up. It's not like if your hot wife finds out what you're doing and leaves you'll sit there for 10 years waiting for another woman that's just as beautiful to show interest. That probably won't be a problem.
