Alec Baldwin and Meryl Streep traded barbs at the Christopher & Dana Reeve Foundation’s gala dinner at Cipriani on Wednesday night. A guest said the act took a bawdy turn when Streep told her “It’s Complicated” co-star, “You truly are one of the most talented and versatile actors of our time, and it was an absolute pleasure getting to see you naked during shooting.” Baldwin replied, “I’d like that in writing.” At the fete honoring Peter D. Kiernan were Mark Ruffalo and Melissa and Joe Gorga.
