Justine Bateman on Arrested Development

Jason Bateman's big sister is going to guest star on one of the final episodes of Arrested Development. Justine Bateman will play Nellie Bluth, who claims to be Michael's long-lost sister, on the show. Michael will hire her to determine whether she really is a blood relative, and then things will inevitably get strange. Not strange, as in brother-and-sister become love interests (as was rumored last year), but I think Justine will just exhibit some unusual behavior. The episode, appropriately enough, is called Family Ties. The cast is filming it right now and it will air on January 9. Another guest star, Scott Baio, is also slated to return to AD as the Bluth family attorney, sometime next month.
