The film's co-producer Arnon Milchan revealed in the book 'Confidential: The Life Of Secret Agent Turned Hollywood Tycoon Arnon Milchan', that Pitt kept the matter hush-hush and stayed with him at his Malibu mansion.
"At first, Jen didn't believe he was involved with Angelina," the Daily Express quoted him as saying in the just published book.
"She started asking around but no one would tell her anything because they were loyal to Brad, so she asked him point blank. He denied it, then eventually admitted he was in love with Angelina.
"Jen was furious and threw him out," he stated.
Milchan also revealed that during that time Pitt, 47, would ride on a motorcycle with a "wraparound helmet with a tinted visor" so that no one would recognize him.
"Brad drove each day to the set, and everywhere else, on a motorcycle and he wore a wraparound helmet with a tinted visor so no one would recognise him. He stayed with me for the duration of filming," he added.
