Continuing her jewel tone and relatively flat-chested red carpet streak, which she kicked off at last weekend's MTV Movie Awards, the 25-year-old stunner opted for a deep green curve-hugging dress with a plunging neckline and thousands of shimmering beads.
The actress completed her 2010 Tony Awards winning look with 13-carat diamond cluster earrings and a 3.5-carat pear-shaped diamond ring, both by Harry Winston, a bouffant updo, smoky purple eyes, pale lips, and bright coral nails.
Daniel Radcliffe and Katie Holmes (wearing a strapless gray chiffon Giorgio Armani Privé gown) presented the award for Best Performance by a Featured Actress in a Play to Johansson, who won for her Broadway debut in Arthur Miller's "A View From the Bridge."
Another big winner of the night was Catherine Zeta-Jones, who took home the award for Best Leading Actress in a Musical for her performance in "A Little Night Music," wearing a pale blue Versace gown (thankfully, sans clogs and scrunchie).
