Angelina Jolie's "rainbow family" of adopted and biological children is not finished yet - not by a long way.
When US chat show host Jon Stewart asked the Hollywood actor how high she and Brad Pitt might go, Jolie said, "It fluctuates between seven and 13 or 14."
Stewart, "Wow, I'll tell you this, I admire that because two is kicking my ass."
Jolie, "Yeah, I understand that. Four is kind of kicking our ass, but we kind of feel like, 'Damn it, we're up for the challenge!'."
Jolie, who is on the promotional trail for her latest film 'A Mighty Heart' has been the subject of reports that she is considering adopting a child in the Czech Republic, where she made her last film. The rumours come only months after she adopted Pax Thien, a three-year-old from Vietnam. His surname was changed to Jolie-Pitt in the US, acknowledging Pitt as his father. The Hollywood stars now have four children - Maddox, Zahara, their biological baby daughter Shiloh, and Pax.
Although 32-year-old Jolie has proudly revealed plans to add to her extensive brood, she and Pitt have been less than enthusiastic about sharing personal details during interviews with journalists. Ahead of her promotions for A Mighty Heart Jolie's representatives insisted each reporter had to sign a contract before speaking to her - whom she told Stewart was "excessive".
A Mighty Heart, which was produced by Pitt, is based on the real-life kidnapping and murder of US journalist Daniel Pearl.
