New Book Reveals Intimate Details On Jennifer & Brad Pitt's Split

Nowadays, things have been looking up for Jennifer Aniston in the love department.

She's been dating Justin Theroux for a little while now, going on vacations and what not, and things seem to be going pretty good for the both of them. Jennifer Aniston And Justin Theroux: Moving In, Matching Rings...

Of course, about six years ago, in the midst of discovering her husband of five years had been cheating on her and then hearing him explain he loved someone else, Jen was likely singing a different tune. And quite honestly, we'd love to leave this sad story in the past where it belongs, but some new insider scoop means we must momentarily dive back into the thick turbulence of yesteryear.

According to The Daily Mail, a new book (entitled Confidential: The Life of Secret Agent Turned Hollywood Tycoon) about Arnon Milchan (who produced Mr & Mrs Smith) provides readers with the ins and outs of a day in the life of a Hollywood producer; and this, it seems, includes knowing quite a bit of personal information about your film's stars and their affairs, giving Arnon a front row seat to the drama that unfolded between Brad Pitt and Jen in their marriage's last days on the set of Mr & Mrs Smith.

As Arnon tells it, Brad originally backed out of the movie early on, when Nicole Kidman was cast to play the role of Mrs. Smith, saying that he felt a "lack of chemistry" between himself and her.

But once Angelina Jolie was recast in the part, Arnon says that Pitt was immediately "infatuated" with her, and that he "called him to say he was happy to play Mr. to her Mrs."

I guess from then on there was a lot of flirting and hanging-out-behind-closed-doors on the set. And it seems Ms. Aniston was aware that something was going on between her husband and his costar when she visited.

Arnon remembers: "At first, Jen didn't believe he was involved with Angelina. 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."

Even after the sinking feelings set in for both Brad and Jen, their marriage still chugged along, and the couple went to the Caribbean with best friends Courtney Cox and David Arquette on a pre-planned trip to celebrate New Years, 2005. Arnon says, though, that the strain was too much and Brad came clean.

"He eventually admitted he was in love with Angelina. Jen was furious and threw him out," the book claims.

After that, Brad returned just once more to the home the couple designed together before moving in with Arnon.

And that was it for their marriage—which up until that point was considered a "success" in Hollywood for lasting five years. Brad has been with Angelina now for over six years.
