Scarlett Johansson: Hollywood's sexiest star with curves that made her famous.

Her curves put her on the map as one of Hollywood’s 𝑠e𝑥iest stars.

But Scarlett Johansson seems to have lost her once-signature trait.

The 28-year-old actress covered up her slimmed-down shape in a conservative black frock by Donna Karan Atelier and a tuxedo jacket as she arrived at the 67th Annual Tony Awards at Radio City Music Hall on Sunday.

But showing she’s no sore loser, the former Tony winner, has taken a break from shooting Captain America: The Winter Soldier to return to the show as a presenter.

Sigourney Weaver, who also failed to win a nomination, is also to present.

But one star who is nominated is Tom Hanks, and he certainly looked delighted as he braved the red carpet with wife Rita Wilson on his arm.
