Angelina Jolie and Brad Pitt are expecting a baby together, according to reports.

A source told the New York Post: "She's just in her first trimester. Obviously they're keeping everything very quiet."

Meanwhile, the Mirror reports that Pitt, currently at Jolie's Buckinghamshire mansion, will be attending the Hyde Park Live 8 event rather than the Philadelphia leg he had previously planned to support.
