Angelina Jolie

As any single woman will tell you, all the good men are taken.
But that makes them all the more attractive, apparently.
Research shows that single women view married men as better catches than bachelors.
The fact that they already have someone's seal of approval adds to their desirability.
The phenomenon, known as 'mate poaching', could perhaps explain why Angelina Jolie fell for Brad Pitt, despite him being seemingly happily married to Jennifer Aniston.
