Would you tell your BFF her husband was a cheater?

Today on The View, the ladies discussed Fox's new show Moment of Truth, which debuts Wednesday. On the show, contestants are hooked up to a lie detector and must truthfully answer 21 questions about themselves in front of their family, friends, co-workers, and a live audience. The promo features an overweight woman asking a contestant, "Do fat people repulse you?" Cringe! Sherri says sometimes people don't want to know the truth--especially concerning their husband's fidelity.

On the Cashmere Mafia pilot episode, Juliet's girlfriends agonized over how to tell her about her cheating husband, only to be shocked that she already knew. If you knew your friend's husband was cheating, would you say something to her about it?
