31. George Clooney
So we have seen George Clooney with his new wife, but he is also lying around with other women. Just take a look at a new Casamigos tequila ad and you will see Clooney under the sheets with Cindy Crawford.
How he/she swings it: Clooney and his actual wife are in an open relationship that allows them both to sleep with other people. Now that simplifies things.
