Jolie's father, Academy Award-winning actor Jon Voight, was a cheater, but she won't be, Sky News reported Saturday.
"To be intimate with a married man, when my own father cheated on my mother, is not something I could forgive," said the star of "Lara Croft: Tomb Raider." "I could not look at myself in the morning if I did that."
Voight left Jolie's mother, Marcheline Bertrand, after he had an affair, when Jolie was a toddler, the Mail reported.
Jolie, who stars in the movie "Mr. And Mrs. Smith" with Pitt, was seen with him in Kenya last month.
