Brad Pitt's Gwyneth film

Brad Pitt's Gwyneth film

The couple - who were an item for over three years and starred in 'Se7en' together - have signed up to star in new political drama 'Dirty Tricks'.

The movie is based on the aftermath of America's Watergate scandal and will also star Annette Bening, Meryl Streep and Sharon Stone.

The scandal rocked America in the 70s when it was revealed Republican President Richard Nixon had been bugging the Democrat headquarters and he resigned as a result.

Brad and Gwyneth will play husband and wife John and Maureen Dean. 'Iris' star Jim Broadbent will play President Nixon.

Filming on the project is scheduled to begin in December.

Gwyneth, 34, once said she regretted splitting from Brad, 43, and admitted she would always only want the best for him.

The Oscar-winning actress is now married to Coldplay star Chris Martin and the couple have a three-year-old daughter, Apple, and a 15-month-old son, Moses, together.

Brad has been in a relationship with Angelina Jolie for over two years. He is father to her three adopted children, Cambodian son Maddox, five, Vietnamese son Pax Thien, three, and Ethiopian daughter Zahara, two.

The couple also have a 14-month-old biological daughter, Shiloh, together.

Brad and Angelina, 32, met on set of action movie 'Mr. and Mrs. Smith' and their romance blossomed shortly after Brad split from his now ex-wife Jennifer Aniston.
