#2 – This A list couple recently married. They were co-stars and then became lovers. Our actor already had a significant other in his life, but he really wanted his co-star. So, he told his then girlfriend he would be working late, got a production assistant to let him into the actresses' trailer and was waiting there for her naked as the day he was born. Unfortunately she was not alone, as her assistant had come with her. The assistant saw what she saw and then went away. Apparently the rest of it worked though since the couple got together.
