Angelina Jolie's recent admission to The NY Times  confirmed what has long been  suspected — Angie  and Brad Pitt fell in love while he was still married to Jennifer Aniston!

Angelina said she'd like to show Mr. & Mrs. Smith to their kids because "not a lot of people get to see a movie where their parents fell in love."

Angie's inflammatory statements ignited a still-simmering powderkeg -- Jen. 

She fired back in The ENQUIRER and their four-year cold war is heating up  — with no end in sight!
