Brad Pitt and Angelina Jolie don't know the sex of their babies?

Oh, c'mon. I firmly believe they don't want the world to know. But are you telling me that after all the close monitoring and ongoing careful testing of those two babies, Mom and Pop weren't sussed to the sex of their unborn twins?

One thing is certain. Boys or girls or one of each, the twins will look tres fashionable for summer 2008 in the white outfits purchased at one of their parents' fave French baby boutiques, Bonpoint, in Cannes.

They recently bought several white ensembles in size 1-3 months. Of the babies' sex, Angelina reportedly told the sales girl, "I don't know yet we don't want to know."

My theory is that she didn't spill the beans on the sex to the inquiring salesgirl because Angelina knew that they'd call People magazine faster than you can say fromage, which is precisely what happened.
