The 66th Annual Tony Awards were given out to the best stars of Broadway last night -- but it was Hollywood's elite that had heads turning on the red carpet.
"The Help" star Jessica Chastain had everyone trying to figure out just how see-thru her nude dress was ... the actress showing off a whole lot of cleavage in a very sheer Marios Schwab number.
Sheryl Crow also made her first public appearance since announcing she has a benign brain tumor ... and she looked great. With flawless hair and makeup, the singer looked sexy in a navy blue gown with crystal embellishments.
The always fashionable Emma Stone looked stunning in white alongside boyfriend and "The Amazing Spider-Man" costar Andrew Garfield ... who was nominated for an award last night.
More Hollywood stars at the event: Hugh Jackman, Ricky Martin, Nick Jonas, Amanda Seyfriend, Stockard Channing, John Stamos, Jesse Tyler Ferguson, James Marsden and more.
