They've both got gorgeous men, adorable kids, super-luxe, globetrotting lives and have graced tons of magazine covers -- but there's a crucial difference between Angelina Jolie and Victoria Beckham.

Pregnant with her fourth child, the Spice Girl turned fashion designer wants a "big family" with hubby David Beckham, she tells CNN's Alina Cho in an interview airing Saturday. But not as big as Jolie and Brad Pitt!

"[If I] don't have a girl this time, then maybe I'll be lucky enough and have a girl the next time," Beckham, 36, told Cho (New York Post's Page Six ran an excerpt of their chat). Beckham has said that she doesn't yet know her unborn child's gender.

Would she really consider a fifth kid? "There could be," the fashionista said. "Who knows?"

What about a sixth?

"Well, I'm not Angelina. I don't know. I mean, come on."
