Reese Witherspoon has boarded Chernin Entertainment's romantic comedy The Beard.

Plot details are being held under wraps, but we do know that newcomer Rebecca Greene will be delivering the script. The term "The Beard" refers to a member of the opposite sex, who plays the role of a homosexual person's heterosexual lover, in order to conceal their sexuality.

The actress is producing with Peter Chernin. Reese Witherspoon is currently shooting Devil's Knot, a film that centers Atom Egoyan's view of the West Memphis Three murder case. She is also involved with Jeff Nichols' indie drama Mud with Matthew McConaughey.

No production details have been released for this project.
