Angelina Jolie loaded up her kids on a Sony-hired Gulfstream IV this afternoon, on her way to the Salt press junket in Cancun.

Brad didn't accompany Angie and the kids on the private plane, but don't worry, looks like Angelina has the help of a nanny while she tends to business in Mexico. Angelina and the kids will apparently stay in Cancun through the July 4th holiday, with Brad possibly joining them later on.

Another person who won't be attending the junket is Salt co-star Liev Schreiber, who headed to Tahiti instead to supposedly take some time to think about his rocky relationship with Naomi Watts!

Liev and Naomi, who have been together for five years and have two sons, have not been getting along lately, a source tells the NY Daily News.

Liev apparently skipped the junket in order to "sort things out mentally." His rep denies that there's anything wrong, saying "Liev went on a diving trip with a group of friends, and his boys are too young to go."

But why schedule a diving trip in the middle of a press junket? Something is definitely fishy...
