After being raised without a religion, Isla converted to Judaism in preparation for her marriage to Sacha Baron Cohen. She studied the religion for three years before she converted to it.
Isla: (defending her film Confessions of a Shopaholic) I do think this film gives out a good message. I think the message is about consumption and debt and it is something we are all learning about at the moment. Obviously the movie was set in a different economic period but it is a redemption story and my character Rebecca Bloomwood learns her lesson.
Isla: (on wearing five-inch heels while filming Confessions Of A Shopaholic to help her get into character) I thought, there's something funny about a shopaholic buying ridiculously high heels and tottering through the comedy. I thought it would be amusing. It was less amusing, actually, when I had to do it every day!
Isla: (following the birth of baby Olive) I definitely feel sexier after having Olive because even though everything's going south and essentially ruined, I feel like I'm a real women now. I'm a mum. I love being a mum, just love it.
