Law & Order: Special Victims Unit star Mariska Hargitay was nominated for a Golden Globe this past weekend, but she wasn't at the ceremony—it turns out she has a pneumothorax, also known as a collapsed lung. TMZ reported that her lung also partially collapsed a few weeks ago and ter rep told the Daily News that Hargitay was not injured during L&O filming and that she will appear in all episodes this season. In other SVU news, Stephanie March, who played assistant district attorney Alex Cabot—until she went into witness protection—is coming back for six episodes. How? The Post's PopWrap explains, "she's no longer in witness protection because the person she was evading died in prison" and fills in for current ADA Kim Greylek (played by Michael McManus), who is in D.C. for an assignment. Tonight's episode is new: "Detective Benson goes undercover as a Madame to investigate the murder of a child prodigy living a double life."
