Although she admitted that she likes to try on the goods, she insisted that she doesn’t let her husband's work influence her style.
'I like to play fashion with him, but I'm nobody's Barbie,' the 45-year-old said.
'I work hard, I make my own living and I love it. I like having financial independence,' she told Redbook. 'I don't ever want to have to depend on anyone completely. But when I have troubles sometimes, it's nice to have someone there to help.'
She recently took a role in animated feature Puss In Boots so that daughter Valentina, four, can watch her. However, she stressed that she isn't abandoning the gritty roles.
'I'm playing the queen of a drug cartel in an Oliver Stone film,' she said. 'He asked if I'd gone 'all soft' because I'm a mother. I said, 'Yes, but I can be the devil if I need to, because after all, I'm an actress'.'
