Jennifer Aniston is certainly looking rough and rugged on the set of her new movie.

On Monday, the 45 year-old actress sported a large scar on her right check as she got into character for her upcoming film "Cake."

Starring alongside Anna Kendrick and Sam Worthington, the former "Friends" actress plays as a woman who joins a support group for chronic pain sufferers after she is involved in a fatal car accident.

In addition to a fierce facial scar, the brunette beauty also donned darker hair, baggy clothes, and minimal makeup for the role.

She isn’t the first star to undergo a major transformation for a role – Charlize Theron and Halle Berry both took home Academy Awards for their respective roles in "Monster" and "Monster’s Ball" after subjecting themselves to unglamorous movie makeunders.
