Angie'e twins speak French!

Brad Pitt And Angelina Jolie's Babies Speak French!
The Jolie-Pitt twins, Knox and Vivienne, are only 2, but they already know French!"They speak more French than English," Angie recently said. "We have a French teacher who's always with them."

The teachers are actually French nannies, an insider says to Life & Style. 

"Because the nannies do so much day-to-day care, the twins naturally speak in French," notes the insider. "But Angie encourages it," adds the insider. "She's always been obsessed with the idea that educated people speak French as a second language."
