After finishing Paparazzo, you will find this mission marked as a "B" on your map with a little question mark, in West Vinewood. It seems he has the scoop on another celebrity, with this one exploring her sexual side. Follow Beverly down the street and into the yard of the celebrity.
When you reach them, he'll hand you the camera and you will need to film the couple. Keep the camera on the woman and eventually you will be found out. This is your cue to run and jump down to the ground where Beverly did. Get in his car and a chase will occur, although you're not driving. What you need to do is keep the camera on the celebrity throughout the whole chase, which will end at the construction area. The mission will end shortly after that.
