Jessica Alba is back as Sin City stripper Nancy Callahan feeling better about baring almost-all than she ever did in her twenties. Here the 33-year-old actress reveals how marriage and motherhood have helped her feel comfortable in her own skin at last and why she's happy to take risks now. Jessica talks about preparing for her raunchy role in Sin City: A Dame to Kill For, her happy home life and why she's not worried about ageing - just as long as she looks hot in a bikini for her husband. There are also nice lines on fashion.
