Since early March, Angelina Jolie has been hard at work shooting the spy thriller Salt around New York. While she's been riding motorcycles and scaling buildings, partner Brad Pitt has had an even tougher job -- taking care of their six kids. And according to multiple reports, the duo's relationship has been strained to the breaking point as a result.

In other words, they could both use a vacation. But when Angelina, 33, finishes shooting Salt at the end of May, Brad, 45, is going right to work on his next movie, the baseball drama Moneyball -- leaving Angie to take over as full-time parent to Maddox, 7, Pax, 5, Zahara, 4, Shiloh, 2, and twins Vivienne and Knox, 10 months. "Brad's dying to get back to work," says an insider close to the couple. "But he's going to be away from the kids for extended periods of time. On the other hand, Angie gets tons of time to bond with the children -- but very little time with their father."
