Pink Cheated on Her Husband with Other Women?

About a week ago, I was telling you that power girl Pink's marriage was officially dead, and that the singer had decided to get a not-so-very-pink divorce from her husband, motocross star Carey Hart. At the time, word on the street (OK, metaphorically) was that the divorce was mainly due to the fact that Pink and her hubby had agreed on an open marriage – that is, a marriage in which they could both "play away from home". In other words, cheating was not such a deadly sin, as long as all the true love was reserved for their respective spouses. Now, I'm not married and I can still tell that this was not the best arrangement in known history. But if it worked for them, I suppose it was OK, at least for a while.
