Los Angeles - Charlize Theron has formed a close friendship with Angelina Jolie.
The Mad Max: Fury Road actress, who is rumoured to be engaged to Sean Penn, has reportedly forged a friendship with her fellow Oscar winner after being introduced by the Maleficent star's husband Brad Pitt.
A source said: "The guys have been tight for years and ever since Sean and Charlize became serious they've been spending a lot of time together as a foursome."
Like Angelina, South African-born Charlize, who has adopted three-year-old son Jackson, is involved in a lot of charity work and deeply respects the 39-year-old actress for raising six children, Maddox, 13, Pax, 11, Zahara, 10, Shiloh, eight and six-year-old twins Knox and Vivienne.
The insider told US OK! magazine: "The girls realised that they have a very similar outlook on life and quickly bonded over everything from their adopted children to their prospective Hollywood projects."
The duo are even hoping to work together on Captain Marvel, the comic giant's upcoming first female-led superhero film.
The source said: "Marvel has been courting Angie to direct the project and Charlize is a clear fan favourite for the starring role. If Charlize were to get the part, Angie would almost certainly sign on to work with her new pal."
