It looks like Johnny Depp and Amber Heard are under the assumption that the couple that stars in films together stays together.

The couple - who met on the set of 2011's The Rum Diary - have signed up to co-star again in the upcoming thriller London Fields. In the thriller - based on Martin Amis' 1989 novel - Heard will play a fortune teller opposite Billy Bob Thornton's terminally-ill ex-pat. Heard's character knows that she will be murdered soon and becomes involved with three different men - one of which is her killer. Theo James and Jim Sturgess have also been slated to co-star.

There's no word yet as to whom the newly-blonde Depp will play.

Filming for the project began in September, with the 50 year old star rumored to have completed most of his scenes between filming his other movies.
