'Twilight' star joins new Oliver Stone film

Twilight actress Mia Maestro has signed up to the cast of Oliver Stone's Savages.

The actress, who will be seen in the next Twilight film as a Covenant vampire, is to play Benicio Del Toro's wife in the adaptation of Don Winslow's novel.

Her character will be "a tough and bitter woman whose soccer mum lifestyle hides a gang-life past", according to The Hollywood Reporter.

The film centres on a pair of drug dealers living in Laguna Beach, who are forced to work for a cartel after their shared girlfriend is kidnapped by the leader.

Maestro will join confirmed cast members Emile Hirsch, Blake Lively, Aaron Johnson, Uma Thurman and John Travolta.

The 33-year old Spanish actress made her Hollywood debut in Frida, the biopic of legendary Mexican artist Frida Kahlo.
