JA is a hottie; I’ve admired here ever since her days on that comedy troupe which preceded FRIENDS....just can’t remember the name.
The Hollywood types want to keep their images on screen. I believe that JA is worried that she’s getting old and doesn’t have the skills of the better actors; hence this scene.
Sadly, this role is a step down for her (unless she wants to enter the adult film industry). I would rather see her play some down and out character that makes it good by working hard and learning hard.
I wonder if JA is trying to make herself more of a bad girl to compete with Angelina.
