AceShowbiz - Angelina Jolie has revealed the reason behind her decision to sell the first photos of her newborn twins, Knox and Vivienne, to magazines in back 2008. The decision, she explains, was driven primarily by safety concerns.

"It's a strange thing to do or to have to do, but it was kind of the better option, but also it was for their safety," Jolie said at the Santa Barbara International Film Festival. "It was that somebody was coming for it and it was a safety concern as well."

The actress and her then-husband, Brad Pitt, donated the $14 million they received from the sale of the photos to their charity, the Jolie-Pitt Foundation.

Jolie also discussed her children's interest in the entertainment industry, revealing that none of them seem to have a strong "affinity" for acting.

"No. I don't know, that's not my doing," Jolie admitted. "I always wanted them to be around film because I wanted them to know as a part of - it's such a wonderful family, to be creative, to be an artist, to be … They're not interested."

She added, "They really don't like any of the celebrity part of it, especially Shiloh hates it."

However, her children have connected to the art of film in other ways. "Yes, they've been on set with me," Jolie continued. "And some of them dance, some of them paint, some of them love theater, but none of them are dying to be on screen."
