Jill Wagner is not a great actress and doesn't have much nude scenes to offer either. Her most explicit role was "Blade: The Series", you can see her naked butt plunging into a pool of blood. That doesn't sound too sexy but thats the most you get to see from her.
Sure she had also some sexy roles and by sexy I mean her in underwear and showing some skin, which might be enough for some guys. So for instance in TV shows like "Stargate: Atlantis" or "Dr. Vegas". If you wan't to see some HD material and hot scenes of her and others just use the provided button.
