Angelina Jolie is being lined up to star in the new Muppets movie. The 33-year-old actress - who is set to give birth to twins later this month - has reportedly been approached to feature in the film because she is such a huge fan of the Jim Henson creations.

A source said: "The idea is to re-launch the Muppets with a big name and a big movie. Angelina is a big Muppets fan and being so passionate about kids there's a very real chance that she'll take this project on. "Even Brad might want to have Miss Piggy as a love interest!" Angelina has previously revealed she thinks she looks like one of the comical puppets.

She said: "I am odd-looking. I sometimes think I look like a funny Muppet!" Angelina already has three adopted children - Maddox, six, Pax, three, and two-year-old Zahara - and a two-year-old biological daughter Shiloh with Brad.

The Muppets started life on their own TV show which was a worldwide hit and eventually spawned a host of movies. Angelina wouldn't be the first celebrity to appear alongside the mischievous puppets. Rocker Alice Cooper, the late Johnny Cash and Diana Ross were all guests on the series.
