Rob Lowe arrives in Washington, begins filming new reality pilot, "Potomac Fever"

Look, it's Rob Lowe! (Carlo Allegri/AP) t's really happening -- again! When word first came last year of a new D.C.-based reality series, "Potomac Fever" -- developed by none other than Rob Lowe -- it seemed no more than a fever dream. Hadn't the nation already glutted itself on the Top Chefs, Housewives and Real Worlders of D.C.? But a TV crew arrived yesterday in the neighborhood of the White House to start filming a pilot about young Washingtonian strivers -- with the blue-eyed producer himself on the scene. Lowe, in jeans and sweater, stood on the sidelines as the cameras filmed a young man and woman in conversation at M.E. Swing Coffee Co. near 17th and G. (Lowe also revved up on two double macchiatos while there.) Unclear who drew the camera's gaze -- but we've learned that the tentative cast includes WUSA-9 reporter Angie Goff, Fresh 94.7
