Brad: I Didn't Cheat On Jen With Angelina

(CBS) For the first time, Brad Pitt has opened up about his relationships with his current wife, Angelina Jolie, and his ex-wife, Jennifer Aniston.

In a surprisingly candid interview with W magazine, Pitt insists he didn't cheat on ex-wife Jennifer Aniston with Angelina Jolie, and says his relationship with Jolie, whom he went on to marry, didn't begin until after he and Aniston split in 2005.

Pitt also defends Aniston's recent comments about Jolie, saying, "I think she got dragged into that one, and then there's a second round to all of that Angie versus Jen. It's so created."

Jolie says she and Pitt fell in love while making the 2005 movie, "Mr. & Mrs. Smith." In November, Aniston depicted Jolie's comments as "really uncool.".

The W article quotes Pitt as saying, "What people don't understand is that we filmed ("Mr. & Mrs. Smith") for a year. We were still filming after Jen and I split up. Even then it doesn't mean that there was some kind of dastardly affair. There wasn't. I'm very proud of the way that it was handled. It was respectful. (The film) will mean something to our kids. It will, that's all."

W's West Coast editor, Kevin West, did the Pitt interview and wrote the piece about it in W.

He discussed the interview, and his impressions of Pitt, on The Early Show Thursday with co-anchor Julie Chen.
