Angelina Jolie seems to have taken a page from Brad Pitt’s media playbook: Get Diane Sawyer to shine the spotlight on African poverty by granting an interview to ABC News. The canny actress, who traveled to Africa recently with economist Jeffrey Sachs, promoted the MTV documentary about their trip by appearing on Good Morning America yesterday. In addition to talking about her humanitarian work, she ladled out some tidbits about her kids — but not, of course, about her romantic life. The MTV show, called The Diary of Angelina Jolie and Dr. Jeffrey Sachs in Africa, premieres tonight, coinciding with the opening of the massive United Nations summit of world leaders in New York. Note to Angelina: I don’t doubt your sincerity, but world leaders might take you a tad more seriously as an antipoverty activist if you didn’t refer to Africa as a ”country.”

Also, Women’s Wear Daily reports that Jolie has signed on with the St. John knitwear line to serve as their new spokesmodel. Knitwear? At least she won’t have to worry about covering her tattoos with makeup.
