Mandy Moore, Kristen Bell, Jessica Biel and more stars rock revealing dresses at the 2017 Golden Globe Awards

The Golden Globe Awards kicked off 2017 award season and the fashion seems to be all about the plunging necklines!

Mandy Moore knocked it out of the park on Sunday in an inky dress from Naeem Khan with a very sexy plunging neckline. The gown showed off every inch of the "This Is Us" star's A-list body. She polished off the look with smoky eyes and tousled tresses.

Jessica Biel also turned heads at the Globes in a stunning dress with a daring neckline. The two-tone dress dipped low in the front with two black straps that went down to the waistline and connected with a belt to a bold, printed skirt. The skirt featured a up-to-there slit and several floral appliques. The unique look was a total standout and Biel finished off the sexy, stylish ensemble with a slicked back chignon.

Kristen Bell proved mom's definitely know how to bring out the sexy with a knockout, black gown. The sparkling, long sleeve gown had a tuxedo lapel detail that reached down to her navel and had a squared off pattern. The overall look was 100 percent sexy and she amped things up with sexy curls and a nude lip color.
