Brad Pitt & Angelina Jolie Over? Movie 'Walk Out' After Sienna Miller 'Flirting' Fight

Angelina Jolie's so angry with hubby Brad Pitt, the beloved 40-year-old actress is filming her new movie abroad to temporarily "escape" her troubled marriage. Bascially, Jolie's using work to slyly "walk out" on Pitt. Really!?

As MstarsNews previously reported, Jolie supposedly "blew up" on her "By The Sea" lover for secretly "flirting" with "The Lost City of Z" starlet, Sienna Miller (while filming in Northern Ireland):

"Angie told him flat out, 'You're not going.' She's heard Brad bring up Sienna's name almost every day since the film went into production in August... Sienna really gets under [Jolie's] skin," an alleged insider tells InTouch. "Brad told her to let him do his job as a producer, and Angelina yelled that she didn't want him near Sienna... They barely talked for the next day."

And now they're on the brink of divorce (again):

"He's told Angie it's over," the source reveals. "He's beyond miserable and wants out... He's come to resent the power he's allowed her to have over him. She was bossy and demanding and humiliated Brad in front of the cast and crew a number of times... [It] pushed Brad over the edge [and] made him think that getting married was a huge mistake - instead of bringing them together, it drove them further apart."

Yeah, right. Miller amusingly denied such crazy "movie crush" rumors during a recent interview with Sway:

"I haven't really read too much about it, but break it down, let's clear it up... So the truth about that rumour is that Brad Pitt is producing the movie that I just wrapped but I haven't seen him. He's not been to the set, he's a producer on the film and I've met him twice, and yeah, it's insane."

So what's the problem now?

Apparently Jolie's filming in Cambodia "for months" in order to avoid the 51-year-old Hollywood heartthrob:

"They're both so fed up with each other that they were almost relieved when she packed up," another seedy tabloid snitch tells OK! magazine. "Brad and Angelina have been living separate lives, and now she's made the first move to leave."

Funny - Jolie's indeed across the world right now, but so is her family! According to GossipCop, Jolie (plus Pitt and their kids) were recently photographed TOGETHER in Cambodia. Another legit source insists that this latest oversensationalized report is simply "not true." Brangelina's still happy and going strong!
