Scarlett Johansson and Denzel Washington celebrated right after winning their Tonys. Johansson (“A View From the Bridge”) and friends headed to Cornerstone for its Sunday night karaoke party. Still in her glittering Elie Saab dress, she sang Billy Joel‘s “New York State of Mind,” Kenny Rogers‘ “Lucille” and Leonard Cohen’s “Hallelujah,” and stayed until 4 a.m. Washington, who took the Best Actor award for “Fences,” headed to 48 Lounge but stuck to Diet Coke.
