According to a couple of reviews, Gaby Hoffman has nude scenes in Crystal Fairy which premiered last night at Sundance.

From Indiewire:

Soon, he's admonishing her for running around naked in their shared hotel room and recoiling at her hairy armpits. Hoffman's admirably passionate delivery goes great lengths to provide Jamie with his ultimate foil. Frequently baring all and never quieting down, her tendency to get a rise out of Jamie provides fodder for an enjoyable mismatch that never fully develops.

From New York Post:

After taking a shower, she hangs out with the boys naked, in one of Sundance’s trademark unsexy nude scenes, and given the tufts under her arms that resemble a Civil War general’s beard, Jamie rechristens her Crystal Hairy.
