Angelina Jolie led her children Pax, Maddox, Shiloh, and Zahara out onto a golf cart yesterday as they prepared to board a private plane out of Cancun. The fivesome arrived in windy Mexico just a few days ago so that Angelina could attend the junket for Salt. Her first order of business was putting on a white Versace dress and getting her hair styled for an outdoor photo call with her costar Chiwetel Ejiofor and director Phillip Noyce. Angelina later headed inside for a press conference to talk about how supportive Brad Pitt was when she decided to get back to work following the 2008 birth of their twins, Knox and Vivienne. It'll be a busy few weeks for Angelina as she continues doing press before her film's July 23 release, but now she'll have a few days off to enjoy a long Fourth of July weekend with her kids.
