BEHATI’S BAREFOOTIN’

Adam Levine’s fiancee, Behati Prinsloo (above), hit the after-party for her man’s new movie, “Begin Again,” where she danced barefoot by the DJ booth for most of the night, we’re told. Our spy also says that the Bowery Hotel bash, held after a screening of the flick, brought out Keira Knightley, Judd Apatow, writer/director John Carney, Joshua Jackson, Brie Larson, Tina Brown, Harry Evans, Coco Rocha, Megan Hilty, Dana Delany, Pablo Schreiber, Isiah Whitlock Jr., Harry Brant and Peter Brant Jr.
