Brad and Angelina fizzle They were once America's sexiest couple, but the passion between Angelina Jolie and Brad Pitt has cooled. "They do love each other," says a pal. "But that wild physical chemistry isn't there anymore." Part of the problem is the pressures of maintaining two high-profile careers and another is their growing family, into which they just welcomed Pax, 3, from Vietnam. "Their relationship has developed so fast that it's almost like they're an old married couple now," says the friend. Brad, says another pal, recently tried to plan an intimate getaway for Angelina and himself - and arranged for his mother, Jane, to babysit their four kids for a few days. But Angelina nixed the idea. "She had other things on her mind," says the friend.
