Brad Pitt has turned to his The Mexican co-star Julia Roberts for advice on raising twins.

The movie hunk is set to become a father again when partner Angelina Jolie delivers twins in France, and reports suggest he has reached out to the Pretty Woman star for some expert advice.

A source tells America's the Globe, "Brad was all frantic about knowing if the rules for twins are different than raising or taking care of single babies. But Julia told him it's the same - only twice as hard."

Jolie checked into a Nice, France hospital on Monday where she will remain until she gives birth. Roberts gave birth to her twins, Phinnaeus and Hazel, three years ago.
