An onlooker told the Sun, “It happened between half six and seven o’clock on Sunday evening. There were a group of people attending a self-help group for the day. Because it was pleasant weather, their leader suggested they move things outside. But during their session they noticed a couple getting rather fruity on a nearby bench. They were kissing and groping each other. Hands were going up clothing and there was lots of groaning. They were practically having full-blown sex. Then people realized it was Moss and Doherty - her skinny blue jeans were the giveaway. But a second later the couple noticed they were being watched and pulled away.�?
