She’s Robin Wright without the Penn and doing just fine, thank you very much. At a post- screening dinner for “The Private Lives of Pippa Lee,” Wright says she didn’t miss acting while raising a family, but is excited to be back with two new movies in the pipeline, including one directed by Robert Redford. She told us she’s lived many lives and has no regrets. Toasting her comeback at Osteria del Circo were pals Julian Schnabel, Robert Wuhl, Harvey Weinstein and Sienna Miller, who told us she’d love another crack at Broadway.
