Yeah. I've hooked up with a few people with sig others as well. I'm not sure if it's entirely the right thing to do, but then, I've done it when i'm single. Also, I don't play for Chelsea or drive for Formula 1, i'm just an ordinary guy, so I can hardly pick and choose
When it comes to being in a relationship, I don't put up with the cheatahs. You can "spot" a "cheatah" a mile away. Groan.
