Aniston talks about 'The Break-Up'

Aniston arrived at the CBS Studios for The Early Show to promote her new movieThe Break-Up

SANTA MONICA, Calif. -- When Jennifer Aniston schedules a press conference, it's a bit like a boxing match.

The gloves are off, she'll roll with the punches and she'll even get a few jabs in herself.

Aniston knew what she was in for when she sat down to discuss her summer comedy The Break-Up.

She knew she couldn't pretend the subject matter wasn't more personal than the usual run-of-the-mill flick.

Aniston agreed to star in The Break-Up during the very public collapse of her marriage to Brad Pitt.

"It was definitely ironic, but it wasn't difficult for me," insists Aniston adding "if anything, it was cathartic. Making the movie helped me through by own (breakup)."

There are several scenes in The Break-Up in which Aniston collapses into tears.

"That was just movie magic. I didn't have to go to any place in my own life for those scenes," she insists.

Just the same, she admits "it was horrible having to do those crying scenes because I had to get myself into a sad place and stay there for a long time."

In the film, Aniston plays a woman obsessed with keeping her condo looking and running like a show home. Her partner, played by Vince Vaughn, is a bit of a slob.

"I'm a little crazy about doing the dishes. I definitely am the type of woman who needs a clean kitchen before I go to bed.

"I probably should ask for more help around the house, but I don't.

"I'm like every other woman who wishes someone would just offer to do the dishes even if I intend to do them myself."

Aniston believes "it's instinctual as a woman to be the caretaker of your home.

"Women complain that men don't do enough, but that's the woman's fault. You train your man to do nothing. You can't blame someone for not knowing what his job should be if you don't ask for it right off the bat.

"There's no sliding into it later."
