BEIJING, Aug. 13 -- Angelina Jolie has been asking adult movie star Tera Patrick for advice on playing Catwoman. The 33-year-old actress - who gave birth to twins Vivienne Marcheline and Knox Leon last month - is said to be good friends with the busty brunette, and believes she can offer an insight into portraying the feline villain in the next Batman movie. A source told the New York Post newspaper: "Tera and Angelina are friends and keep in touch via e-mail. They have a girl-talk thing going. After seeing reports that she'll land the lead role, Angelina asked Tera what she thought. Tera had such insights into the role that Angelina cracked, 'You should do it!' "

Since welcoming the twins, her fifth and sixth children with partner Brad Pitt, into the world last month, Angelina has been approached to star in a variety of movies including 'The Thomas Crown Affair 2' alongside Pierce Brosnan - a role for which movie bosses want her to put on weight.
