If so, she was mighty chatty about it. And chatty secret agents don't survive long.
Ah, but she did almost die in an explosion.
Plus, why kill a supermodel that is known to have psychological problems. Anything she says won't be believed.
But i agree, she probably wasn't a real agent. Although she could still have done things like like mail something or deliver a package. She'd be in a perfect position to be a delivery agent. Superstars travel a lot and are rarely suspected to be secret agents.
