Alba.... But my first choice in Hollywood would be Charlize Theron. 2nd choice - Natalie Portman.
Angelina is got a very sensual face and nice tits, but that all because she is got ugly chicken legs and a very flat behind. Jessica doesn't match Angelina in the hot department, but her total package makes her the winner for me. If I was to do it with Angelina then I would like her to be on top and if it was with Alba then I would love to spoon her dry.
