Christian wouldn't have been able to contain himself! Dakota Johnson attended Hollywood Foreign Press Association's Annual Grants Banquet in Beverly Hills, Calif., on Thursday, Aug. 13, where she steamed up the scene in a sultry ensemble.

The Fifty Shades of Grey actress, 25, rocked a navy-blue Dior coatdress, complete with oversized accent buttons at the hips, plus ankle-strap Casadei sandals and Meira T ear jackets. She swept her Anastasia Steele-brunette locks up into a tousled updo, and lined her blue peepers, making them pop.

But of course, she wasn't the only fashionable A-lister at the event. Hitting the red carpet one day before her 49th birthday, Halle Berry stunned in a cutout, cerulean Noam Hanoch dress, joined together by pieces of black lace, and heels by Jimmy Choo.

Elizabeth Banks brought a pop of color to the scene in a coral Roksanda dress, accented by turquoise and lavender stripes, which she accessorized with a clutch and purple heels by Jimmy Choo. 

Meanwhile, Sophia Bush kept things classic in a Smythe tuxedo-style LBD, teamed with an Edie Parker clutch and Casadei heels.

And who could ignore the best-dressed men of the night? Sofia Vergara's fiancé, Joe Manganiello, sizzled in an all-black ensemble. Tangled's Zachary Levi worked a gray three-piece suit with a red tie. And Andrew Garfield took his new mustache out for a night on the town while clad in a midnight Dior Homme suit, paired with a striped button-up.

Last but not least, the carpet's cutest couple, Emily Blunt and John Krasinski, arrived arm in arm in complementary styles. While the Into the Woods actress modeled a Michael Kors halter dress, two-toned heels, a Milly clutch, and earrings by EF Collection, her husband cut a fine figure in a gray suit, finished with a licorice tie.
