Brad Pitt And Angelina Jolie At War?

"Brad Pitt has been grounded by his helicopter instructor," claims Star magazine.

Angelina Jolie reortedly "splashed out nearly $1.6 million on a helicopter and flying lessons" for Pitt earlier this year.

Now Jolie has now "forbidden Brad from taking to the air!"

"Angie has made it clear that Brad is not to fly until he's certified, but Pax and Maddox have been begging to go for a ride," says a Star insider. "Brad asked the instructor, but he was very much against it."

Maddox "ratted Brad out to Angie" , and "the house turned into World War III!"

Pitt eventually "smoothed things over" with Jolie.
