No, this isn't a joke about her recent tabloid drama, guys. We're totally better than that. Kristen Stewart has joined 'Lie Down in Darkness,' the latest film from Scott Cooper, writer and director of 'Crazy Heart.'

THR reports that Stewart has signed on to play the part of Peyton Loftis in the adaptation of William Styron's 1951 novel of the same name. It's a dark, dramatic story of a frigid mother who lavishes all of her love and attention on her crippled daughter, while ignoring her emotionally damaged and beautiful daughter, Peyton. The mother also ignores her drunken husband, pushing him to lust after Peyton.

It's a challenging role for Stewart, who was last seen in 'Snow White and the Huntsman' opposite Charlize Theron and Chris Hemsworth. She can be seen next in 'The Twilight Saga: Breaking Dawn -- Part 2,' which hits theaters this November and thus concludes the agonizing saga of the sparkling vampires (for now), and 'On the Road,' the adaptation of the Jack Kerouac novel, which premiered at Cannes in May but still has no official US release date as of yet.

'Lie Down in Darkness' currently has no financing and is still seeking a male lead for the role of the drunken father who wants to have gross sex with one of his own daughters -- a real gem of a role for any would-be Oscar contenders, we're sure.
