Robin Wright is doing just fine without Sean Penn. The actress has dropped Penn from her name and turned her blond hair brown. She wowed guests at the star-studded Cinema Society screening of her movie “The Private Lives of Pippa Lee” on Sunday night. Showing off her slim figure in a Herve Leger dress, she was overheard saying, “This is all about new beginnings for me.” Wright was seen chatting with writer/director Rebecca Miller and husband Daniel Day-Lewis at the packed party at the Breslin attended by stars, including Penelope Cruz, Marion Cotillard and Billy Crudup. Her co-star Blake Lively, accompanied by boyfriend Penn Badgley, was also the talk of the evening in a plunging white jacket. But Lively admitted she still gets nervous seeing herself on screen. She told Page Six: “I loved the role, but it is hard to watch myself with so many people in the theater.”
