I've heard Brad say in numerous interviews, that he couldn't wait to become a father. I famously remember him telling Oprah during the junket for "Troy", that he wanted all girls and that he couldn't wait to have little Jennifers running around. The women in the audience went crazy.
During an interview with Diane Sawyer for Ocean's Twelve, Brad and George Clooney jokingly interviewed each other. Brad asked Clooney, "When are you getting married again?" and Clooney asked Brad, "When are you going to become a father?" I remember thinking that Jennifer was going to be ticked when she saw that, because it seemed as if Brad was pressuring her to have a child.
I've often wondered how an "okay-looking" chick like Jennifer Aniston managed to land someone like Brad Pitt. Pity she couldn't hold on to him.
