ACM Awards 2018: Prettiest gowns on the red carpet

Country's biggest stars partied hard in Sin City! The annual ACM Awards took place on Sunday night, and celebrities hit the red carpet dressed to the nines.

Nicole Kidman stole the show from hubby Keith Urban in a glittering gold Michael Kors gown, while Miranda Lambert was a stunner in a red Georges Chakra number. A number of stars chose leg-baring looks for the occasion, with Maren Morris choosing a bold Christian Siriano strapless dress and Julia Michaels opting for a pretty pastel look.

But the spotlight wasn't just on the country stars themselves, their spouses also stole the show in their gorgeous dresses. Luke Bryan's wife Caroline looked drop-dead gorgeous in a ravishing red gown with a plunging neckline, while Dierks Bentley's ladylove Cassidy was a vision in a pearl-encrusted white gown. What stunners!
