Chris Martin Who? Gwyneth Paltrow Stands by Her Woman

Amid reports of a shaky marriage, her Goopness signs on to play Nicole Kidman's wife in the story of the world's first postop transsexual, The Danish Girl

Nicole Kidman is apparently man enough for Gwyneth Paltrow. (The jury's still out on whether a certain Coldplay frontman can lay claim to the same.)

Her Goopness has signed on to play the wife of the world's first postoperative transsexual in The Danish Girl, the long-in-the-works film adaptation of the same-named novel by David Ebershoff.

She replaces Charlize Theron in the role of Greta, a portrait painter in the 1920s who encourages her husband to dress up and sit as her female model. The resulting artwork becomes wildly popular, her husband realizes he has more than a penchant for his womanly alter ego and, presto, big-time change-o, Kidman's man turns into a woman.

Oscar, are you listening?

Let the Right One In's Tomas Alfredson directs the film, which has yet to set a start date pending financing.
