Grasping for answers and hoping to bring some much-needed order to a world plunged into chaos by Sean Penn and Robin Wright's split after 11 years of marriage, an anonymous source describes a possibly meaningful incident in which a tarted-up Sienna Miller sat in the actor's lap at a NY party. Titillated yet? What if we told you that during that lap-sitting, Miller had her arm around his neck? A ha! Fortunately for all parties involved, a "Penn friend" dismissed the idea that the actress was somehow involved in the break-up, disclosing that the actress has a tendency to "drape herself over people she likes." See, she's just drapey! You may now return to snipe-hunting for clues about why the couple ended their relationship in old movie footage. [Rush & Molloy]
