Jennifer Aniston Will Never Know if Brad Pitt Cheated With Angelina Jolie  8/4/05

Jennifer Aniston will never know if her estranged husband Brad Pitt cheated on her with Angelina Jolie.

In an interview with Vanity Fair magazine, Aniston says she believes Pitt's claims nothing happened between him and his Mr & Mrs Smith co-star before they ended their marriage in January (05).

But she had suspicions about the nature of Pitt and Jolie's relationship after photographs emerged of the pair holidaying with Jolie's adopted son Maddox.

Vanity Fair journalist Leslie Bennetts, who interviewed Aniston, says, "She said to me 'I'll never really know.'"
